Calciphylaxis is rare, life-threatening calcific uremic arteriolopathy in patients with end stage renal disease. Rarely, it can occur in patients with normal renal function known as non-uremic calciphylaxis. Very scant literature and few case reports are available about non-uremic calciphylaxis.

Introduction: In any given population, coronary artery diameter is highly variables. It has been postulated that Indians have an increased risk of coronary artery disease (CAD) due to smaller diameter of arteries in them. However, small diameter can be due to smaller body surface area (BSA). Hence, we tried to assess whether smaller coronary artery dimensions in Indians are due to their smaller BSA or not. Methodology: In this observational study, patients undergoing computed tomography coronary angiography and having normal angiogram were included in this study. Patients' coronary artery diameters in major epicardial vessels were measured and indexed to BSA. Analysis was done to assess for any significance compared to Caucasians. Results: A total of 250 patients were part of this study. The mean diameters of proximal left main (LM), distal LM, left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA) were 4.27 ± 0.78, 4.26 ± 0.79, 3.47 ± 0.6, 2.99 ± 0.64, and 3.33 ± 0.63 mm, respectively. On indexing to BSA, the measurements in proximal LM, distal LM, LAD, LCX, and RCA were 2.31 ± 0.4, 2.31 ± 0.4, 1.89 ± 0.32, 1.62 ± 0.35, and 1.81 ± 0.34 mm/BSA, respectively. When they were compared to other Indian and Caucasian studies, the diameters were not found to be statistically significant. Conclusion: Thus, the authors conclude that Indians do not have an increased risk for CAD because of their smaller diameters, but it is because of their smaller BSA. This study helped us evaluate the reference range of major epicardial vessel diameters in Indian population.

Blood pressure (BP), even in healthy normotensive individuals, is dynamic, varies with a circadian periodicity, and is influenced by physiological and environmental factors. Abnormal 24-h BP patterns have been observed in many patients with hypertension (HTN), which may be overlooked if evaluations are based only on office BP measurements. Out of office BP measurements, such as Ambulatory Blood Pressure Monitoring and Home Blood Pressure Monitoring (ABPM and HBPM) is important for optimal BP management and are better predictors of adverse outcomes. However, HTN diagnosis and management are often based on relatively few clinic BP measurements, and there are no recommendations to guide clinicians managing patients with abnormal 24-h BP patterns in India. Thus, the present consensus statement aims to provide uniform evidence-based recommendations for the diagnosis and management of abnormal 24-h BP patterns. Strategies for screening for HTN based on the current prevalence trends in India have been suggested. Further, recommendations on the appropriate use of ABPM and HBPM in diagnosis and management of HTN are provided.

Background and Aims: It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown. Aim was to study the prevalence of familial hypercholesterolemia(FH) in young patients of coronary artery disease admitted to department of Cardiology of Sir Ganga Ram hospital, New Delhi.

AimsThe prevalence of premature coronary artery disease (CAD) in India is two to three times more than other ethnic groups. Untreated heterozygous familial hypercholesterolemia (FH) is one of the important causes for premature CAD. As the age advances, these patients without treatment have 100 times increased risk of cardiovascular (CV) mortality resulting from myocardial infarction (MI). Recent evidence suggests that one in 250 individuals may be affected by FH (nearly 40 million people globally). It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown.MethodsA total of 635 patients with premature CAD were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Based on scores, patients were diagnosed as definite, probable, possible, or no FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded.ResultsOf total 635 patients, 25 (4%) were diagnosed as definite, 70 (11%) as probable, 238 (37%) as possible, and 302 (48%) without FH, suggesting the prevalence of potential (definite + probable) FH of about 15% in the North Indian population. FH is more common in younger patients, and they have lesser incidence of common CV risk factors such as diabetes, hypertension, and smoking than the younger MI patients without FH (26.32% vs.42.59%; 17.89% vs.29.44%; 22.11% vs.40.74%).ConclusionFH prevalence is high among patients with premature CAD admitted to a cardiac unit. To detect patients with FH, routine screening with simple criteria such as family history of premature CAD combined with hypercholesterolemia, and a DLCN criteria score >5 may be effectively used.

Our aim was to evaluate the temporal changes in left ventricular (LV) diastolic filling in relation to other LV parameters using cardiac MRI (CMR) in patients with HER2 positive breast cancer receiving trastuzumab therapy. Fourty-one women with early stage HER2+ breast cancer underwent serial CMR (baseline, 6, 12, and 18 months) after initiation of trastuzumab therapy. A single, blinded observer measured LV parameters on de-identified CMRs in random order. Linear mixed models were used to investigate temporal changes. Compared to baseline, there were significant decreases in systolic function as measured by both left ventricular ejection fraction (LVEF) (p <0.001 at 6 and 12 months) and peak ejection rate corrected for end-diastolic volume (PER/LVEDV) (p = 0.008 at 6 months, p = 0.01 at 12 months). However, these differences were no longer significant at 18 months. In contrast, significant reductions in diastolic function as measured by LV peak filling rate corrected for end-diastolic volume (PFR/LVEDV) were observed at 6 months (p = 0.012), 12 months (p = 0.031), and up to 18 months (p = 0.034). There were no significant temporal changes in the time to peak filling rate corrected for cardiac cycle (TPF/RR). The reduction in PFR/LVEDV at 18 months was no longer significant when corrected for heart rate. In conclusion, there were significant subclinical deleterious effects on both LV systolic and diastolic function among patients receiving trastuzumab. While there was recovery in LV systolic function after therapy cessation at 18 months, reduction in PFR/LVEDV appeared to persist. Thus, diastolic dysfunction may serve as a marker of trastuzumab-induced cardiotoxicity that needs to be confirmed in a larger study.

ObjectivePrimary objective was to compare the effects of atorvastatin 40mg vs 80mg on LDL-C in Indian patients with atherosclerotic dyslipidemia. Secondary objectives were to compare the effects of atorvastatin 40mg vs 80mg on HDL-C and triglycerides and also comparing of side effects (myopathy, hepatotoxicity and new onset diabetes mellitus) of both doses.MethodThis Study is A Prospective, randomized, open-label, comparative study. This study was conducted on 240 patients of dyslipidemia (as per ACC/AHA 2013 lipid guidelines) attending the OPD/wards/CCU of department of cardiology, Sir Ganga Ram Hospital. They were randomly divided into 2 groups of 120 each. Group A consisted patients who received Atorvastatin 40mg daily and Group B Atorvastatin 80mg daily. The follow up period was 6 months.ResultsAt 3 and 6 month follow up, Atorvastatin 40mg leads to mean LDL cholesterol reduction of 47.18±20.81 & 50.03±18.06 respectively. While Atorvastatin 80mg results in LDL reduction as 50.11±15.85 & 52.30±13.72. The comparison between two doses revealed a non-significant difference (p=.118 & p=.149 respectively).At 6 months of follow up, few patients reported myalgia (2 in group A and 7 in Group B). The difference between groups was significant (p=.045). Although none of our patient had significant elevation of CPK.ConclusionThis study concluded that both doses of atorvastatin (40 & 80mg) are equally efficacious in improving dyslipidemia but higher dose leads to more incidence of myalgia.

We are describing a case of repeated interventions performed during long-term follow-up. To the best of our knowledge, this is the only case report of 1 closed mitral valvotomy followed by 3 time balloon mitral valvotomy culminating ultimately to mitral valve replacement in 41 year follow-up.

Yoga is an ancient Indian mind body technique which is becoming increasingly popular throughout the world because of its several health benefits. Yoga is an integrated system of self culture which aims at harmonious development of body, mind and covers all aspects of human life that lead to physical well being, mental harmony culminating into positive thinking, happiness and peace. Yoga envisages health in totality on the principle of healthy mind in a healthy body. Yoga is not merely a few postures (asanas) but a holistic life style which promotes physical, mental, emotional and spiritual well being.1 Although there are many types of yoga, Hatha Yoga is most commonly practiced. Core components of Hatha Yoga include stretching exercises and physical postures (Asanas), breath control (Pranayama) and concentration techniques (Meditation). Yoga is believed to help detoxify the body, mitigate chronic fatigue, enhance endurance, improve organ and immune functions.2 Beneficial effects of yoga have been reported in multiple chronic conditions including depression, stress, anxiety, menopausal symptoms, arthritis, low back pain, cancer, allergies, asthma, acid peptic disease, irritable bowel syndrome, migraine, metabolic syndrome, diabetes mellitus, cardiovascular diseases (CVD) etc.3–5 Yoga appears to be especially beneficial for primary and secondary prevention of CVD.

Ghee (clarified butter) has generally been assumed to be hypercholesterolaemic on the basis of its composition but there is hardly any study to support or refute the assumption. The present study was conducted on sixty-three healthy, young, physically active adult volunteers (52 male, 11 female). The study design was that of a randomized controlled trial with a parallel design. After a lead-in period of 2 wk, the subjects were randomly divided into two groups, Group A (n = 30; 25 male, 5 female) and Group B (n = 33; 27 male, 6 female). Group A (experimental) consumed for 8 wk a diet in which ghee provided 10% of the energy intake. The only other visible fat in the diet was mustard oil, and total energy from fats was 25% of the energy intake. Group B (control) consumed for 8 wk a similar diet except that all visible fat came from mustard oil. The serum total cholesterol level showed a significant rise in the experimental group at 4 wk; the rise persisted at 8 wk. A similar rise was also seen in HDL cholesterol. Hence the total cholesterol/HDL cholesterol ratio did not show any significant change. In the control group, there was a trend towards a fall in LDL cholesterol but the change was not significant. The study does not indicate any adverse effect of ghee on lipoprotein profile. However, more studies are needed on older subjects, hyperlipidaemic subjects, and on subjects following less healthy lifestyles before the results of this study can be extrapolated to the general population.

This study investigated the differential effect of losartan, an AT1 receptor blocker, when administered in pre- and postischemic phases, on the biochemical, hemodynamic and oxidative stress associated with regional ischemic-reperfusion injury in cat. Losartan (5 microg/kg/min) or normal saline was administered intravenously in open chest barbiturate anesthetized cats, 15 min before and 10 min after the occlusion of the left anterior descending (LAD) coronary artery. The LAD was occluded for 15 min followed by 60 min reperfusion. In the saline treated group, there was significant depression of hemodynamic functions, i.e., mean arterial pressure (MAP), heart rate (HR), left ventricular end diastolic pressure (LVEDP) and left ventricular (LV) peak (+/-) dP/dt, along with depletion of adenosine triphosphate (ATP) of the affected myocardium. Oxidative stress during reperfusion injury was evidenced by significant increase in plasma thiobarbituric acid reactive substances (TBARS) accompanied by significant reduction in myocardial superoxide dismutase (SOD) activities. In both treatment groups, losartan caused recovery of all the hemodynamic parameters and repletion of ATP along with no significant change in plasma TBARS and myocardial SOD activity. There was no effect on catalase activity. Results from the study suggest that the effects of pre- and posttreatment of losartan are comparable in functional recovery of the heart from ischemic-reperfusion injury.

Various population studies have reported the association of rare S2 allele of apolipoprotein C3 ( APOC3 ) SstI polymorphism with hypertriglyceridemia (HTG) and coronary artery disease (CAD). We were the first to report an association of S2 allele with high triglyceride (TG) levels in healthy volunteers from Northern India. Since HTG is suggested to be a predominant risk factor for CAD among Indians, we have elucidated the relationship of APOC3 SstI polymorphism with the lipid profile and CAD. A total of 158 patients with ≥ 70% stenosis in one or more coronary artery (angiographically proven CAD patients), 35 subjects with < 70% stenosis (NCAD) and 151 normal controls (free of heart disease) from Northern plains of India were recruited in the study. DNA samples were analyzed by polymerase chain reaction (PCR) followed by SstI digestion. Lipid profile was estimated by enzymatic kit. We found a strong association of S2 allele with high TG levels, which was more significant in patients. Prevalence of S2 allele in normal controls and CAD patients were comparable, despite the fact that mean TG level was significantly higher in patients. A greater insight into this observation revealed that the prevalence of high TG, if not coupled with other risk factors (like high total cholesterol, low HDL), was comparable in patients and controls. Thus, our study reveals that rare S2 allele may be employed as a susceptibility marker for high TG. However, high TG or S2 allele alone may not contribute to the etiology of CAD.

Thirty four healthy young volunteers (22 men, 12 women; age 25.7 +/- 5.8 years; BMI 20.8 +/- 2.3 kg/m2) participated in a randomized controlled cross-over trial on the effect of consuming one boiled egg every day for 8 wk on the serum lipid profile. The only significant change after 8 wk of egg consumption was an elevation of the total cholesterol/HDL cholesterol ratio. However, scrutiny of individual responses revealed that twelve of the subjects (10 men, 2 women) had a greater than 15% rise in the LDL cholesterol level after 8 wk of egg consumption. These subjects, considered hyperresponders, showed significant increases (P < 0.025) at both 4 wk and 8 wk after egg consumption in total cholesterol and LDL cholesterol levels, and at 8 wk in total cholesterol/HDL cholesterol ratio. The remaining 22 hyporesponders showed no change in any of the variables measured at 4 wk or 8 wk after egg consumption. In view of the high nutritional value of eggs, a blanket ban on eggs is not justified. However, since up to one-third of the population may be hyperresponders, knowing the response of an individual is important before making the egg a regular item of the diet.

Several studies including a small case-control (hypertriglyceridemic/normotriglyceridemic individuals) study by us revealed close association between rare S2 allele ofAPOC3 Sstl polymorphism and hypertriglyceridemia. With the understanding that Asian Indians are highly vulnerable to the adverse effects of hypertriglyceridemia, we extended the investigation and studied the frequency distribution of this polymorphism in 216 healthy volunteers from Northern plains of India. We found that more than 50% of the study population had one or two S2 allele. This may suggest that a larger fraction of this population is genetically predisposed to hypertriglyceridemia.
