Introduction: Mental health diagnoses such as depression, post-traumatic stress disorder (PTSD), and anxiety are common after acute cardiovascular events. Peripartum cardiomyopathy (PPCM) affects women near the end of pregnancy or in the near post-partum period and occurs during a period of heightened psychosocial stress. There is limited data on the prevalence of mental health diagnoses after the acute PPCM event. Methods: Patients with self-identified PPCM enrolled in the online PPCM Registry (PPCM-R at ppcmr.org) and completed validated surveys for depression (Patient Health Questionnaire - 9, PHQ-9), anxiety (Generalized Anxiety Disorder -7, GAD-7), PTSD ( Posttraumatic Stress Disorder Checklist- Civilian, PCL-C) and quality of life (Rand SF-36). Patients were recruited on PPCM support groups, social media, and physician referral. Results: After 4 months, 103 patients enrolled and 55 (54%) completed the mental health and QOL surveys. Mean age was 32.3 (SD 4.7) and median time since diagnosis was 4.2 years (IQR 1.7, 10.4 years). Mean (SD) PHQ-9 score was 8.1 (7.3) and 27% had a score (≥10) indicating moderate or severe depressive symptoms. Mean (SD) GAD-7 score was 7.3 (6.7) and 36% of participants had scores (≥10) consistent with moderate or severe anxiety symptoms. Mean (SD) PCL-C score was 20.7 (19.3) and 33% screened positive for PTSD. Overall, 30% of participants reported that QOL was ‘fair’ or ‘poor’ with lower domain scores for physical function, emotional function, energy/fatigue and general health compared to the general population. Characteristics of participants stratified by mental health symptom severity and QOL scores are presented in the Table. Conclusions: Half (51%) of participants had at least one mental health screening tool which indicated current moderate or severe symptoms of depression, anxiety or PTSD. These findings confirm a significant burden of mental health symptoms in this PPCM survivor cohort.

The United States is the only developed country in the world in which peripartum maternal mortality is increasing. ECMO (Extracorporeal Membrane Oxygenation) has been used with increasing success as a tool to support circulatory or respiratory failure in the non-pregnant patient. The reported data

OBJECTIVE: Our objective was to examine the appropriateness of cardiac troponin (cTn) testing among patients with cTn increases. METHODS: This is a planned secondary analysis of the Use of TROPonin In Acute coronary syndromes (UTROPIA, NCT02060760) observational cohort study. Appropriateness of cTn testing was adjudicated for emergency department patients with cTn increases >99th percentile and analyzed using both contemporary and high-sensitivity (hs) cTnI assays according to sub-specialty, diagnoses, and symptoms. RESULTS: Appropriateness was determined from 1272 and 1078 adjudication forms completed for 497 and 422 patients with contemporary and hs-cTnI increases, respectively. Appropriateness of cTnI testing across adjudication forms was 71.5% and 72.0% for cTnI and hs-cTnI, respectively. Compared with emergency physicians, cardiologists were less likely to classify cTnI orders as appropriate (cTnI: 79% vs 56%, P < .0001; hs-cTnI: 82% vs 51%, P < .0001). For contemporary cTnI, appropriateness of 95%, 70%, and 39% was observed among adjudication forms completed by cardiologists for type 1 myocardial infarction, type 2 myocardial infarction, and myocardial injury, respectively; compared with 90%, 86%, and 71%, respectively, among emergency physicians. Similar findings were observed using hs-cTnI. Discordance in appropriateness adjudication forms occurred most frequently in cases of myocardial injury (62% both assays) or type 2 myocardial infarction (cTnI 31%; hs-cTnI 23%). CONCLUSIONS: Marked differences exist in the perception of what constitutes appropriate clinical use of cTn testing between cardiologists and emergency physicians, with emergency physicians more likely to see testing as appropriate across a range of clinical scenarios. Discordance derives most often from cases classified as myocardial injury or type 2 myocardial infarction. (C) 2019 Published by Elsevier Inc.

BACKGROUND:We aimed to characterize the clinical and pathologic findings of aortic dissection (AD) over a nearly 60-year period.METHODS:The Jesse E. Edwards Registry of Cardiovascular Disease database was queried for cardiac specimens from autopsies with AD as a diagnosis and compared 2 cohorts: early (1956-1992) and current (1993-2015).RESULTS:From 1956 to 2015, 338 cases (166 early, 170 current) with AD were included (mean age: 60; 62% male). The AD was 86% type A and 14% type B. Sixty-two percent of cases were under medical care at time of death (61% early, 62% current, P = not significant). Of those under medical care, 63% were not diagnosed prior to death (64% early, 62% current, P = not significant). Risks for dissection did not differ between time intervals and include left ventricular hypertrophy, suggestive of hypertension (84%), prior cardiovascular surgery (38%), bicuspid valve (14%), and connective tissue disease (9%). An intimal tear was identified in the ascending aorta in the majority (68%), followed by descending (14%), root (9.5%), and arch (7%). Aortic rupture occurred in 58%, most frequently in the ascending aorta (41%).CONCLUSIONS:In a large cardiovascular registry, >60% of cases of AD were not detected clinically and first identified at autopsy. Although diagnostic techniques have significantly improved over the time interval, the percentage of AD discovered at autopsy did not differ from the early to the current era. The most prevalent risk factors for dissection including hypertension and prior cardiovascular surgery remain similar in both time periods. AD death is related to rupture of the aorta in the majority of cases.

BackgroundStudies addressing patients with type 2 myocardial infarction and myocardial injury, including the impact of using high-sensitivity (hs) cardiac troponin (cTn) assays on their incidence are needed.MethodsOurs is a prospective, observational US cohort study. Consecutive emergency department patients with serial cTnI measurements were studied. Outcomes included 180-day mortality and major adverse cardiac events, including 2-year follow-up for those with myonecrosis.ResultsAmong 1640 patients, using a contemporary cTnI assay, 30% (n = 497) had ≥1 cTnI >99th percentile, with 4.7% (n = 77), 8.5% (n = 140), and 17% (n = 280) classified as type 1 myocardial infarction, type 2 myocardial infarction, and myocardial injury, respectively. Compared with patients without myonecrosis, 180-day mortality was higher for type 2 myocardial infarction (4% vs 13%, P < .0001) (adjusted hazard ratio 2.7; 95% confidence interval, 1.6-4.8; P = .0005) and myocardial injury (4% vs 11%, P < .0001) (adjusted hazard ratio 1.8; 95% confidence interval, 1.1-3.0; P = .02), both with mortality >20% at 2 years. Predictors of 2-year mortality for type 2 myocardial infarction included age, congestive heart failure, and beta-blockers. Relative to the contemporary cTnI assay, hs-cTnI had less myonecrosis (30% vs 26%, P = .003) and acute myocardial infarction (13.2% vs 10.8%, P = .032), including fewer type 2 myocardial infarctions (8.5% vs 6.3, P = .01), with no difference in myocardial injury (17% vs 15%, P = .1).ConclusionscTnI increases are encountered in approximately a third of patients, the majority due to nonatherothrombotic conditions. Compared with patients without myonecrosis, type 2 myocardial infarction and myocardial injury have worse short-term outcomes, with mortality rates >20% at 2 years. hs-cTnI assay does not lead to more myocardial injury or infarction.

Background: Aortic dissection (AD) is characterized by diverse clinical manifestations and as a result, diagnosis is often delayed or not recognized until autopsy. Despite significant advances in imaging and the knowledge from clinical registries such as IRAD, the diagnosis is often still missed.

BACKGROUND We examined the diagnostic performance of high-sensitivity cardiac troponin I (hs-cTnI) vs contemporary cTnI with use of the 99th percentile alone and with a normal electrocardiogram (ECG) to rule out acute myocardial infarction (MI) and serial changes (deltas) to rule in MI. METHODS We included consecutive patients presenting to a US emergency department with serial cTnI onclinical indication. Diagnostic performance for acute MI, including MI subtypes, and 30-day outcomes were examined. RESULTS Among 1631 patients, MI was diagnosed in 12.9% using the contemporary cTnI assay and in 10.4% using the hs-cTnI assay. For ruling out MI, contemporary cTnI ≤99th percentile at 0, 3, and 6 h and a normal ECG had a negative predictive value (NPV) of 99.5% (95% CI, 98.6-100) and a sensitivity of 99.1% (95% CI, 97.4-100) for diagnostic and safety outcomes. Serial hs-cTnI measurements ≤99th percentile at 0 and 3 h and a normal ECG had an NPV and sensitivity of 100% (95% CI, 100-100) for diagnostic and safety outcomes. For ruling in MI, contemporary cTnI measurements had specificities of 84.4% (95% CI, 82.5-86.3) at presentation and 78.7% (95% CI, 75.4-82.0) with serial testing at 0, 3, and 6 h, improving to 89.2% (95% CI, 87.1-91.3) by using serial cTnI changes (delta, 0 and 6 h) >150%. hs-cTnI had specificities of 86.9% (95% CI, 85.1-88.6) at presentation and 85.7% (95% CI, 83.5-87.9) with serial testing at 0 and 3 h, improving to 89.3% (95% CI, 87.3-91.2) using a delta hs-cTnI (0 and 3 h) >5 ng/L. CONCLUSIONS hs-cTnI and contemporary cTnI assays are excellent in ruling out MI following recommendations predicated on serial testing and the 99th percentile with a normal ECG. For ruling in MI, deltas improve the specificity. ClinicalTrials.gov Identifier: NCT02060760.

BACKGROUNDInternational Classification of Diseases (ICD) coding is the standard diagnostic tool for healthcare management. At present, type 2 myocardial infarction (T2MI) classification by the Universal Definition of Myocardial Infarction (MI) remains ignored in the ICD system. We determined the concordance for the diagnosis of MI using ICD-9 coding vs the Universal Definition.METHODSCardiac troponin I (cTnI) was measured by both contemporary (cTnI) and high-sensitivity (hs-cTnI) assays in 1927 consecutive emergency department (ED) patients [Use of TROPonin In Acute coronary syndromes (UTROPIA) cohort] who had cTnI ordered on clinical indication. All patients were adjudicated using both contemporary and hs-cTnI assays. The Kappa index and McNemar test were used to assess concordance between ICD-9 code 410 and type 1 MI (T1MI) and type 2 MI (T2MI).RESULTSAmong the 249 adjudicated MIs using the contemporary cTnI, only 69 (28%) were ICD-coded MIs. Of 180 patients not ICD coded as MI, 34 (19%) were T1MI and 146 (81%) were T2MI. For the ICD-coded MIs, 79% were T1MI and 21% were T2MI. A fair Kappa index, 0.386, and a McNemar difference of 0.0892 (P < 0.001) were found. Among the 207 adjudicated MIs using the hs-cTnI assay, 67 (32%) were ICD coded as MI. Of the 140 patients not ICD coded as MI, 27 (19%) were T1MI and 113 (81%) were T2MI. For the ICD-coded MIs, 85% were T1MI and 15% T2MI. A moderate Kappa index, 0.439, and a McNemar difference of 0.0674 (P < 0.001) were found.CONCLUSIONSICD-9-coded MIs captured only a small proportion of adjudicated MIs, primarily from not coding T2MI. Our findings emphasize the need for an ICD code for T2MI.

Supply-demand type 2 myocardial infarction (T2MI) is frequently encountered. Little is known about gender differences in patients with T2MI in contrast to type 1 MI (T1MI) and non-MI troponin (cTn) increases. We sought to compare mortality according to gender among these groups. Retrospective study

Supply/demand (type 2) myocardial infarction is a commonly encountered clinical challenge. It is anticipated that it will be detected more frequently once high-sensitivity cardiac troponin assays are approved for clinical use in the United States. We provide a perspective that is based on available data regarding the definition, epidemiology, etiology, pathophysiology, prognosis, management, and controversies regarding type 2 myocardial infarction. Understanding these basic concepts will facilitate the diagnosis and treatment of these patients as well as ongoing research efforts.

Aims: To determine the ability of serial cardiac troponin (cTnI) changes (delta) to distinguish type 1 and type 2 myocardial infarction (MI) (excluding all ST-segment elevation MIs (STEMIs)) and describe the diagnostic accuracy and 180-day mortality in MI versus no-MI patients. Methods and results: Serial cTnIs were measured in 1112 consecutive patients without STEMI and within 6h of presentation to a United States emergency department: 856 (77%) with no MI, 66 (6%) type 1 MI, and 190 (17%) type 2 MI. Of the 0 to 3h and 0 to 6h absolute and relative cTnI changes, only the distribution of absolute change from 0 to 6h was significantly different between type 1 and type 2 MI: median (interquartile range) 311 (1430) ng/l vs. 80 (330) ng/l, p=0.03. Neither the absolute concentration change nor the absolute percent change from either 0 h to 3h (areas under the curves (AUCs) 0.57 and 0.54 respectively) or 0 h to 6h (AUCs 0.60 and 0.51) improved on the performance of the individual cTnI results at 3h (AUC 0.60) or 6h (AUC 0.62), respectively. After adjusting for age, and histories of heart failure and renal insufficiency, those with type 2 MI (hazard ratio 2.9, 95% confidence interval (CI) 1.4–5.9, p=0.004) and those with no index MI and cTnImax0–6h > 34 ng/l (2.5, CI 1.1–6.0, p=0.04) had increased risk of death within 180 days compared with those with no MI and cTnImax 0–6h ≤ 34 ng/l. Conclusion: Delta cTnI did not aid in distinguishing type 1 MI from the more common type 2 MI. Patients diagnosed with type 2 MIs, which represented more than half of all index MIs, had increased risk of death after discharge.
