PURPOSE:Layer-specific global longitudinal strain (GLS) may provide important insights in patients with suspected coronary artery disease (CAD). We aimed to investigate the association between layer-specific GLS and coronary artery calcium score (CACS) in patients suspected of CAD. METHODS:We performed a retrospective study of patients suspected of CAD who underwent both an echocardiogram and cardiac computed tomography (median 42 days between). Layer-specific (endocardial-, whole-layer-, and epicardial-) GLS was measured using speckle tracking echocardiography. We assessed the continuous association between layer-specific GLS and CACS by negative binomial regression, and the association with high CACS (≥400) using logistic regression. RESULTS:Of the 496 patients included (mean age 59 years, 56% male), 64 (13%) had a high CACS. Those with high CACS had reduced GLS in all layers compared to those with CACS < 400 (endocardial GLS: -20.5 vs. -22.7%, whole-layer GLS: -17.7 vs. -19.4%, epicardial GLS: -15.3 vs. -16.9%, p < .001 for all). Negative binomial regression revealed a significant continuous association showing increasing CACS with worsening GLS in all layers, which remained significant after multivariable adjustment including SCORE chart risk factors. All layers of GLS were associated with high CACS in univariable analyses, which was consistent after multivariable adjustment (endocardial GLS: OR = 1.11 (1.03-1.20); whole-layer GLS: OR = 1.14 (1.04-1.24); epicardial GLS: OR = 1.16 (1.05-1.29), per 1% absolute decrease). CONCLUSION:In this study population with patients suspected of CAD and normal systolic function, impaired layer-specific GLS was continuously associated with increasing CACS, and decreasing GLS in all layers were associated with presence of high CACS.

Context Cholesterol carried in lipoprotein(a) adds to measured low-density lipoprotein cholesterol (LDL-C) and may therefore drive some diagnoses of clinical familial hypercholesterolemia (FH). Objective We investigated plasma lipoprotein(a) in individuals referred to Danish lipid clinics and evaluated the effect of plasma lipoprotein(a) on a diagnosis of FH. Methods Individuals referred to 15 Danish lipid clinics who were suspected of having FH according to nationwide referral criteria were recruited between September 1, 2020 and November 30, 2021. All individuals were classified according to the Dutch Lipid Clinical Network criteria for FH before and after LDL-C was adjusted for 30% cholesterol content in lipoprotein(a). We calculated the fraction of individuals fulfilling a clinical diagnosis of FH partly due to elevated lipoprotein(a). Results We included a total of 1166 individuals for analysis, of whom 206 fulfilled a clinical diagnosis of FH. Median lipoprotein(a) was 15 mg/dL (29 nmol/L) in those referred and 28% had lipoprotein(a) greater than or equal to 50 mg/dL (105 nmol/L), while 2% had levels greater than or equal to 180 mg/dL (389 nmol/L). We found that in 27% (55/206) of those fulfilling a clinical diagnosis of FH, this was partly due to high lipoprotein(a). Conclusion Elevated lipoprotein(a) was common in individuals referred to Danish lipid clinics and in one-quarter of individuals who fulfilled a clinical diagnosis of FH, this was partly due to elevated lipoprotein(a). These findings support the notion that the LPA gene should be considered an important causative gene in patients with clinical FH and further support the importance of measuring lipoprotein(a) when diagnosing FH as well as for stratification of cardiovascular risk.

BACKGROUND In patients with non-ST-segment elevation acute coronary syndrome (NSTEACS), coronary pathology may range from structurally normal vessels to severe coronary artery disease. OBJECTIVES The purpose of this study was to test if coronary computed tomography angiography (CTA) may be used to exclude coronary artery stenosis $50% in patients with NSTEACS. METHODS The VERDICT (Very Early Versus Deferred Invasive Evaluation Using Computerized Tomography in Patients With Acute Coronary Syndromes) trial (NCT02061891) evaluated the outcome of patients with confirmed NSTEACS randomized 1:1 to very early (within 12 h) or standard (48 to 72 h) invasive coronary angiography (ICA). As an observational component of the trial, a clinically blinded coronary CTA was conducted prior to ICA in both groups. The primary endpoint was the ability of coronary CTA to rule out coronary artery stenosis ($50% stenosis) in the entire population, expressed as the negative predictive value (NPV), using ICA as the reference standard. RESULTS Coronary CTA was conducted in 1,023 patients-very early, 2.5 h (interquartile range [IQR]: 1.8 to 4.2 h), n = 583; and standard, 59.9 h (IQR: 38.9 to 86.7 h); n = 440 after the diagnosis of NSTEACS was made. A coronary stenosis $50% was found by coronary CTA in 68.9% and by ICA in 67.4% of the patients. Per-patient NPV of coronary CTA was 90.9% (95% confidence interval [CI]: 86.8% to 94.1%) and the positive predictive value, sensitivity, and specificity were 87.9% (95% CI: 85.3% to 90.1%), 96.5% (95% CI: 94.9% to 97.8%) and 72.4% (95% CI: 67.2% to 77.1%), respectively. NPV was not influenced by patient characteristics or clinical risk profile and was similar in the very early and the standard strategy group. CONCLUSIONS Coronary CTA has a high diagnostic accuracy to rule out clinically significant coronary artery disease in patients with NSTEACS.

Studies suggest cardiac time intervals to be associated with cardiac ischemia. A novel method to assess cardiac time intervals by tissue Doppler echocardiography has been proposed. Cardiac time intervals can assess the myocardial performance index (MPI), which quantifies the proportion of time spent contributing effective myocardial work. We hypothesized that MPI associates with coronary artery lesions detected by cardiac computed tomography (CT) in patients suspected of coronary artery disease (CAD).

BACKGROUND:Coronary microvascular dysfunction (CMD) may cause angina in the absence of obstructive coronary artery disease (CAD) and increases the risk of future adverse cardiovascular events. Transthoracic Doppler echocardiography (TTDE) with pharmacological stress can assess coronary flow velocity reserve (CFVR), a measure of coronary microvascular function. However, simpler methods would be preferable for diagnosing CMD. Therefore, we examined the relationship between CFVR and cardiac time intervals measured by TTDE in a cohort of women with angina and no obstructive CAD. METHODS:In a prospective cohort study, we included 389 women with angina, left ventricular ejection fraction > 45%, and no obstructive CAD. CMD was defined as CFVR < 2.0. The study population was divided into three groups according to cutoff values of CFVR < 2, 2 ≤ CFVR ≤ 2.5, and CFVR > 2.5. Isovolumic contraction time (IVCT), ejection time (ET), and isovolumic relaxation time (IVRT) were measured by tissue Doppler M-mode, and the myocardial performance index (MPI = (IVCT + IVRT)/ET) was calculated. RESULTS:Coronary microvascular dysfunction was associated with increasing age, hypertension, higher resting heart rate, and lower diastolic blood pressure. Moreover, CMD was associated with higher E/e' ratio (P = 0.002) and longer IVCT (P < 0.001), higher MPI (P < 0.001) and shorter ET (P = 0.002), but not with IVRT or conventional measures of left ventricular geometry, mass, and function. In multivariable analysis, longer IVCT (P < 0.001) and higher MPI (P = 0.002) remained associated with CMD. CONCLUSION:In women with angina and no obstructive CAD, CMD is associated with longer IVCT and higher MPI indicating a link between CMD and subtle alternations of systolic and combined measures of cardiac time intervals.

Postsystolic shortening (PSS) by speckle-tracking echocardiography (STE) is a marker of myocardial ischemia and may improve diagnostic strategy. We sought to evaluate if PSS is associated with the coronary artery calcium score (CACS) and stenosis by computed tomography angiography (CTA) in patients with suspected stable angina pectoris (SAP). We retrospectively studied 437 SAP patients (age 58 ± 11 years, 41% male) who underwent STE, evaluation of CACS and assessment of significant stenosis (≥ 50%) by CTA. The postsystolic index (PSI) was defined as follows: 100x([peak negative strain cardiac cycle − peak negative strain systole])/peak negative strain cardiac cycle. A wall had PSS if any segment within the wall had a PSI ≥ 20%. We defined categories for walls with PSS: 0, 1, 2 and ≥ 3, and CACS: 0, 1–100, 101–400 and > 400. Each additional wall with PSS was associated with a 43% relative increase in CACS (95%CI +9% to +87%, P = 0.010), while each 1% absolute increase in the PSI was associated with a 9% relative increase in CACS (95%CI +1% to +18%, P = 0.031). Walls with PSS (OR 1.81 per 1 wall increase, 95%CI 1.27–2.59, P = 0.001) and the PSI (OR 1.12 per 1% increase, 95%CI 1.04–1.21, P = 0.004) were associated with the occurrence of CACS > 400. Additionally, walls with PSS (OR 1.53 per 1 wall increase, 95%CI 1.21–1.93, P < 0.001) was a predictor of significant stenosis by CTA. PSS is associated with CACS and significant stenosis by CTA in patients with SAP and may aid in the selection of patients referred for cardiac computed tomography.

Cardiovascular disease is the most common comorbidity in type 1 diabetes. However, current guidelines do not include routine assessment of myocardial function. We investigated whether echocardiography provides incremental prognostic information in individuals with type 1 diabetes without known heart disease. A prospective cohort of individuals with type 1 diabetes without known heart disease was recruited from the outpatient clinic. Follow-up was performed through Danish national registers. The association of echocardiography with major adverse cardiovascular events (MACE) and the incremental prognostic value when added to the clinical Steno T1D Risk Engine were examined. A total of 1093 individuals were included: median (interquartile range) age 50.2 (39.2–60.3) years and HbA1c 65 (56–74) mmol/mol; 53% men; and mean (SD) BMI 25.5 (3.9) kg/m2 and diabetes duration 25.8 (14.6) years. During 7.5 years of follow-up, 145 (13.3%) experienced MACE. Echocardiography significantly and independently predicted MACE: left ventricular ejection fraction (LVEF) <45% (n = 18) vs ≥45% (n = 1075), HR (95% CI) 3.93 (1.91, 8.08), p < 0.001; impaired global longitudinal strain (GLS), 1.65 (1.17, 2.34) (n = 263), p = 0.005; diastolic mitral early velocity (E)/early diastolic tissue Doppler velocity (e′) <8 (n = 723) vs E/e′ 8–12 (n = 285), 1.59 (1.04, 2.42), p = 0.031; and E/e′ <8 vs E/e′ ≥12 (n = 85), 2.30 (1.33, 3.97), p = 0.003. In individuals with preserved LVEF (n = 1075), estimates for impaired GLS were 1.49 (1.04, 2.15), p = 0.032; E/e′ <8 vs E/e′ 8–12, 1.61 (1.04, 2.49), p = 0.033; and E/e′ <8 vs E/e′ ≥12, 2.49 (1.41, 4.37), p = 0.001. Adding echocardiographic variables to the Steno T1D Risk Engine significantly improved risk prediction: Harrell’s C statistic, 0.791 (0.757, 0.824) vs 0.780 (0.746, 0.815), p = 0.027; and net reclassification index, 52%, p < 0.001. In individuals with type 1 diabetes without known heart disease, echocardiography significantly improves risk prediction over and above guideline-recommended clinical risk factors alone and could have a role in clinical care.

Tissue Doppler, speckle tracking and strain imaging / Left ventricular mechanics 157 was measured from regional strain curves for each segment, as the time from the beginning of the Q-wave to the time-to-peak (sys) (TPS), mechanical dyssynchrony was estimated as TPS-SD.From 12-lead surface ECG, QT interval, QT dispersion, and its corrected values were measured.According to QT(c) (QT(c) ≥440 or <440 ms), patients were categorized into two groups: long QT and normal QT HCM.In the long QT group, QT(cd) and CT in all left ventricular (LV) segments were significantly prolonged; (sys) and SR(sys) were markedly attenuated compared with the other two groups (P<0.001).LV dyssynchrony was significantly greater (P<0.001) and PSS was more frequent in long QT HCM compared with the other two groups (P<0.001).TPS-SD was correlated positively with QT(c) (r=0.38,P<0.01) and QT(cd) (r=0.45,P<0.001).QT(c) ≥440 ms identified LV mechanical dyssynchrony with 70% sensitivity, 100% specificity, and positive predictive value.QT interval prolongation on surface ECG shows significant association with mechanical dyssynchrony and LV dysfunction in HCM.This may add pathophysiological insight into understanding ECG changes in such myocardial disease

Background: The optimal timing of invasive coronary angiography (ICA) and revascularization in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) is not well defined. We tested the hypothesis, that a strategy of very early invasive coronary angiography (ICA) and possible revascularization within 12 hours of diagnosis, is superior to an invasive strategy performed within 48-72 hours in terms of clinical outcomes. Methods: Patients admitted with clinical suspicion of NSTE-ACS in the Capital Region of Copenhagen, Denmark were screened for inclusion in the VERDICT trial (ClinicalTrials.gov NCT02061891). Patients with ECG changes indicating new ischemia and/or elevated troponin, in whom ICA was clinically indicated and deemed logistically feasible within 12 hours, were randomized 1:1 to ICA within 12 hours or standard invasive care within 48-72 hours. The primary endpoint was a combination of all-cause death, non-fatal recurrent myocardial infarction, hospital admission for refractory my...

Aims We hypothesized that the modified Diamond-Forrester (D-F) prediction model overestimates probability of coronary artery disease (CAD). The aim of this study was to update the prediction model based on pre-test information and assess the model's performance in predicting prognosis in an unselected, contemporary population suspected of angina. Methods and results We included 3903 consecutive patients free of CAD and heart failure and suspected of angina, who were referred to a single centre for assessment in 2012-15. Obstructive CAD was defined from invasive angiography as lesion requiring revascularization, >70% stenosis or fractional flow reserve <0.8. Patients were followed (mean follow-up 33 months) for myocardial infarction, unstable angina, heart failure, stroke, and death. The updated D-F prediction model overestimated probability considerably: mean pre-test probability was 31.4%, while only 274 (7%) were diagnosed with obstructive CAD. A basic prediction model with age, gender, and symptoms demonstrated good discrimination with C-statistics of 0.86 (95% CI 0.84-0.88), while a clinical prediction model adding diabetes, family history, and dyslipidaemia slightly improved the C-statistic to 0.88 (0.86-0.90) (P for difference between models <0.0001). Quartiles of probability of CAD from the clinical prediction model provided good diagnostic and prognostic stratification: in the lowest quartiles there were no cases of obstructive CAD and cumulative risk of the composite endpoint was less than 3% at 2 years. Conclusion The pre-test probability model recommended in current ESC guidelines substantially overestimates likelihood of CAD when applied to a contemporary, unselected, all-comer population. We provide an updated prediction model that identifies subgroups with low likelihood of obstructive CAD and good prognosis in which non-invasive testing may safely be deferred.

Background: The optimal timing of invasive coronary angiography (ICA) and revascularization in patients with non-ST-segment elevation acute coronary syndrome is not well defined. We tested the hypothesis that a strategy of very early ICA and possible revascularization within 12 hours of diagnosis is superior to an invasive strategy performed within 48 to 72 hours in terms of clinical outcomes. Methods: Patients admitted with clinical suspicion of non-ST-segment elevation acute coronary syndrome in the Capital Region of Copenhagen, Denmark, were screened for inclusion in the VERDICT trial (Very Early Versus Deferred Invasive Evaluation Using Computerized Tomography) ( ClinicalTrials.gov NCT02061891). Patients with ECG changes indicating new ischemia or elevated troponin, in whom ICA was clinically indicated and deemed logistically feasible within 12 hours, were randomized 1:1 to ICA within 12 hours or standard invasive care within 48 to 72 hours. The primary end point was a combination of all-cause death, nonfatal recurrent myocardial infarction, hospital admission for refractory myocardial ischemia, or hospital admission for heart failure. Results: A total of 2147 patients were randomized; 1075 patients allocated to very early invasive evaluation had ICA performed at a median of 4.7 hours after randomization, whereas 1072 patients assigned to standard invasive care had ICA performed 61.6 hours after randomization. Among patients with significant coronary artery disease identified by ICA, coronary revascularization was performed in 88.4% (very early ICA) and 83.1% (standard invasive care). Within a median follow-up time of 4.3 (interquartile range, 4.1–4.4) years, the primary end point occurred in 296 (27.5%) of participants in the very early ICA group and 316 (29.5%) in the standard care group (hazard ratio, 0.92; 95% CI, 0.78–1.08). Among patients with a GRACE risk score (Global Registry of Acute Coronary Events) >140, a very early invasive treatment strategy improved the primary outcome compared with the standard invasive treatment (hazard ratio, 0.81; 95% CI, 0.67–1.01; P value for interaction=0.023). Conclusions: A strategy of very early invasive coronary evaluation does not improve overall long-term clinical outcome compared with an invasive strategy conducted within 2 to 3 days in patients with non-ST-segment elevation acute coronary syndrome. However, in patients with the highest risk, very early invasive therapy improves long-term outcomes. Clinical Trial Registration: URL: https://www.clinicaltrials.gov .

AimsStable angina is the most common presentation of heart disease and has a good prognosis. With declining coronary artery disease (CAD), rates a diagnostic approach balancing costs and benefits is a challenge, particularly in women. This study describes the real-life diagnostic workup in a large hospital to explore whether the diagnostic approach may be improved.Methods and resultsWe identified 4028 patients free of CAD, referred for and assessed with non-invasive (NIT) or invasive test for stable suspected CAD in 2012-15. In both the sexes, the majority (>85%) presented with chest pain as primary symptom. Women had more non-angina (60.2 vs. 54.5%) and less typical angina (8.2 vs. 11.8%, P < 0.001). Despite a mean pretest probability of 20.9% in women and 45.1% in men (P < 0.001), only 69 (3.1%) women and 190 men (10.4%) were diagnosed with obstructive CAD. In all, 93% underwent a NIT and 80% of these were normal. Among the 1238 men and 1595 women with non-angina or dyspnoea, only 6.1% and 2.9%, respectively, had positive NIT. After multiple adjustments, women remained less likely to have positive NIT [odds ratio (OR) 0.42 95% confidence interval (95% CI 0.32-0.56)] and given a positive test also less likely to have obstructive CAD [OR 0.30 (0.17-0.52)]. The C-statistics for predicting positive NIT was 0.77 (0.72-0.82) in women and 0.77 (0.74-0.80) in men.ConclusionThese data confirm the very low diagnostic yield of non-invasive and invasive assessment of CAD in current clinical practice, particularly in women and in patients with atypical symptoms. Data call for a more rational approach to avoid unnecessary testing.

Objectives: We aimed to determine the prevalence of echocardiographic abnormalities and their relation to clinical characteristics and cardiac symptoms in a large, contemporary cohort of patients with type 2 diabetes. Results: A total of 1030 patients with type 2 diabetes participated. Echocardiographic abnormalities were present in 513 (49.8%) patients, mainly driven by a high prevalence of diastolic dysfunction 178 (19.4%), left ventricular hypertrophy 213 (21.0%) and left atrial enlargement, 200 (19.6%). The prevalence increased markedly with age from 31.1% in the youngest group (<55 years) to 73.9% in the oldest group (>75 years) (p < 0.001) and was equally distributed among the sexes (p = 0.76). In univariate analyses, electrocardiographic abnormalities, age, body mass index, known coronary heart disease, hypertension, albuminuria, diabetes duration and creatinine were associated with abnormal echocardiography along with dyspnoea and characteristic chest pain (p < 0.05 for all). Neither of the cardiac symptoms nor clinical characteristics had sufficient sensitivity and specificity to accurately identify patients with abnormal echocardiography. Conclusion: Echocardiographic abnormalities are very common in outpatients with type 2 diabetes, but neither cardiac symptoms nor clinical characteristics are effective to identify patients with echocardiographic abnormalities.

BackgroundGlobal longitudinal systolic strain (GLS) has recently been demonstrated to be a superior prognosticator to conventional echocardiographic measures in patients after myocardial infarction (MI). The aim of this study was to evaluate the prognostic value of regional longitudinal myocardial deformation in comparison to GLS, conventional echocardiography and clinical information.MethodIn total 391 patients were admitted with ST-Segment elevation myocardial infarction (STEMI), treated with primary percutaneous coronary intervention and subsequently examined by echocardiography. All patients were examined by tissue Doppler imaging (TDI) and two-dimensional strain echocardiography (2DSE).ResultsDuring a median-follow-up of 5.3 (IQR 2.5-6.1) years the primary endpoint (death, heart failure or a new MI) was reached by 145 (38.9%) patients. After adjustment for significant confounders (including conventional echocardiographic parameters) and culprit lesion, reduced longitudinal performance in the anterior septal and inferior myocardial regions (but not GLS) remained independent predictors of the combined outcome. Furthermore, inferior myocardial longitudinal deformation provided incremental prognostic information to clinical and conventional echocardiographic information (Harrell's c-statistics: 0.63 vs. 0.67, p = 0.032). In addition, impaired longitudinal deformation outside the culprit lesion perfusion region was significantly associated with an adverse outcome (p<0.05 for all deformation parameters).ConclusionRegional longitudinal myocardial deformation measures, regardless if determined by TDI or 2DSE, are superior prognosticators to GLS. In addition, impaired longitudinal deformation in the inferior myocardial segment provides prognostic information over and above clinical and conventional echocardiographic risk factors. Furthermore, impaired longitudinal deformation outside the culprit lesion perfusion region seems to be a paramount marker of adverse outcome.

Background: Coronary flow velocity reserve (CFVR) measured by transthoracic Doppler echocardiography is a noninvasive measure of microvascular function, but it has not achieved widespread use, mainly because of concerns of validity and feasibility. The aim of this study was to describe the feasibility and factors associated with the quality of CFVR obtained in a large prospective study of women suspected of having microvascular disease.Methods: Women with angina-like chest pain and no obstructive coronary artery disease on coronary angiography (<50% stenosis) were consecutively examined by transthoracic Doppler echocardiography of the left anterior descending coronary artery to measure CFVR (n = 947). Quality was evaluated on the basis of (1) identification of the left anterior descending coronary artery, (2) maintained probe position throughout the examination, (3) visibility and configuration of the left anterior descending coronary artery in two-dimensional color Doppler mode, and (4) gradual, consistent increases of characteristic, well-defined flow velocity curves in pulsed-wave mode.Results: The mean age (SD) was 62.1 +/- 9.7 years. On the basis of the evaluations, patients were divided into four groups according to quality score: nonfeasible (n = 28 [3%]), low quality (n = 80 [8%]), medium quality (n = 451 [48%]), and high quality (n = 388 [41%]). Quality score was associated with diabetes (P < .01), body mass index (P = .02), waist circumference (P = .05), nonsignificant atherosclerosis on coronary angiography (P = .03), and operator experience (P < .01). Low examination quality was associated with lower CFVR (P = .03), also after multivariate adjustment.Conclusions: Transthoracic Doppler echocardiographic measurement of CFVR is highly feasible and of good quality in experienced hands. However, CFVR is possibly underestimated when examination quality is low. Awareness of pitfalls and potential bias may improve the validity and interpretation of the measures obtained.

Purpose: Cardiovascular disease is the most common cause of mortality in type 1 diabetes; patients with albuminuria are at greatest risk. We investigated myocardial function and premature myocardial impairment in type 1 diabetes patients with and without albuminuria compared to controls. Methods: This study included a cross-sectional survey of 1093 type 1 diabetes patients from Steno Diabetes Center and 200 healthy controls. Conventional and tissue Doppler echocardiographic measurements were analysed in multivariable models in normoalbuminuria ( n = 760), microalbuminuria ( n = 227) and macroalbuminuria ( n = 106). Investigators were blinded to degree of albuminuria. Results: For the type 1 diabetes patients, mean age was 49.6 years, 53% were men and mean diabetes duration was 25.5 years. In multivariable models systolic velocity s′ did not differ between type 1 diabetes patients with normoalbuminuria and controls (β-coefficient [95% confidence interval]: −0.17 [−0.41; 0.08], p = 0.19), but was impaired between controls and microalbuminuria (−0.53 [−0.84; −0.23], p = 0.001) and macroalbuminuria (−0.59 [−0.96; −0.22], p = 0.002). Diastolic measurements ( e′, a′, e′/ a′, and E/ e′) were all significantly impaired in type 1 diabetes, for example, e′/ a′: normoalbuminuria, microalbuminuria and macroalbuminuria versus controls: −0.38 [−0.52; −0.23], p < 0.001; −0.49 [−0.67; −0.32], p < 0.001; and −0.81 [−1.03; −0.59], p < 0.001. In age-related analyses, myocardial impairment occurred prematurely in type 1 diabetes compared to controls (e.g. E/ e′ = 8; 9.2 years [normoalbuminuria], 17.3 years [microalbuminuria] and 41.4 years [macroalbuminuria] prematurely, respectively). Conclusion: In type 1 diabetes patients with albuminuria, both systolic and diastolic functions are impaired, whereas in patients without albuminuria only diastolic function is affected. Myocardial impairment is detectable many years prematurely in type 1 diabetes, especially in patients with albuminuria.

Background: Angina pectoris is the most common symptom of coronary artery disease (CAD) among women but large studies have indicated low diagnostic yield of invasive coronary angiography (ICA). It is well accepted that women have more atypical symptoms and that some tests perform less well in women. Purpose: To examine whether symptoms and non-invasive test result (NIT) are less predictive of obstructive CAD in women compared to men in a large city hospital. Methods: Patients referred for assessment of stable CAD in 2012-2014 in a single center were included. Information on symptoms, risk factors, results of NIT and ICA was gathered from registries and patient records. Ability of symptoms and NIT result to predict obstructive CAD in men and women was compared in multiple adjusted logistic regression models by testing for statistical interaction. Results: A total of 2763 patients were included, 1462 (53%) women. Women were older (59.1 vs 56.4 years, p<0.0001), more likely to have non-anginal chest pain and...
