Clinical, Demographic, and Angiographic Profiles of Amarnath Pilgrims Presenting With Acute Coronary Syndrome.

INTRODUCTION: The challenges posed by high altitude are particularly significant in terms of cardiovascular health. There are currently no data available on acute coronary syndrome (ACS) among Amarnath pilgrims. The objective of this study was to investigate the clinical and angiographic profiles of ACS among Amarnath pilgrims, focusing on demographic characteristics, risk factors, types of ACS, clinical presentation, angiographic findings, and in-hospital outcomes. By examining these aspects, we aimed to provide insights into the unique challenges faced by pilgrims during their spiritual journey and to identify potential strategies for improving the prevention and management of ACS in this population.  Methods: This was a hospital-based, prospective, observational study that included patients who had participated in the pilgrimage and presented with ACS between 2022 and 2023.  Results: Sixty patients were recruited for the study, with a mean age of 51.19 ± 11.17 years. Of these, 43 (71.7%) were male. Risk factors identified in the study included hypertension in 35 (58.3%), smoking in 23 (38.3%), diabetes mellitus in 18 (30%), and dyslipidemia in 25 (41.6%) patients. ST-elevation myocardial infarction (STEMI) was present in 46 (76.66%) patients, Anterior wall myocardial infarction (AWMI) occurred in 29 (48.3%), inferior wall myocardial infarction (IWMI) in 15 (25%), and high lateral wall myocardial infarction (HLWMI) in two (3.3%) patients. Of the 60 patients, 19 (31.6%) were in Killip class I, 16 (26.6%) were in class II, and 25 (41.6%) were in classes III or IV. The average time from the onset of symptoms to hospitalization was 7.6 ± 3.1 hours, significantly higher in those with Killip class III or IV (9.3 ± 3.6 vs. 5.4 ± 2.7 hours, p = 0.01). There were nine (15%) in-hospital deaths, and in the multivariate analysis, advanced Killip class (p = 0.04) and delays in hospitalization of more than six hours (p = 0.03) were found to be significant predictors of mortality. CONCLUSION: In conclusion, 40% of patients presented in the advanced Killip class, and 15% experienced in-hospital mortality. The average time from the onset of symptoms to hospitalization was significantly higher for those categorized in the advanced Killip classes. Our study highlights a significant association between advanced Killip class, delay in hospitalization, and in-hospital mortality among Amarnath pilgrims with ACS, underscoring the importance of timely intervention. It is recommended that appropriate measures be taken to improve patient outcomes in these cases.

Unraveling the Variability of Essential Oil Composition in Different Accessions of Bunium persicum Collected from Different Temperate Micro-Climates.

The present investigation was performed to evaluate the variability of the essential oil composition present in the seed extract of Kala zeera (Bunium persicum Bioss.) obtained from different geographical zones of Northwestern-Himalayan using Gas Chromatography-Mass Spectrum (GC-MS). The results of the GC-MS analysis revealed significant differences in the essential oil content. Significant variability was observed in the chemical constituents of the essential oils mainly for p-cymene, D-limonene, Gamma-terpinene, Cumic aldehyde and 1, 4-p-menthadien-7-al. Among these compounds, the highest average percentage across the locations was observed for gamma-terpinene (32.08%) which was followed by cumic aldehyde (25.07%), and 1, 4-p-menthadien-7-al (15.45%). Principal component analysis (PCA) also grouped the 4 highly significant compounds i.e., p-Cymene, Gamma-Terpinene, Cumic aldehyde, and 1,4-p-Menthadien-7-al into same cluster which are mainly distributed in Shalimar Kalazeera-1, and Atholi Kishtwar zones. The highest value of gamma-terpinene was recorded in Atholi accession (40.66%). However, among climatic zones Zabarwan Srinagar and Shalimar Kalazeera-1 was found to have highly positive significant correlation (0.99). The cophenetic correlation coefficient (c) was found to be 0.8334 during hierarchical clustering for 12 essential oil compounds showing that our results are highly correlated. Network analysis also showed the overlapping pattern and similar interaction between the 12 compounds as shown by hierarchical clustering analysis. From the results, it could be concluded that existence of variability among the various bioactive compounds of B. persicum which are probably to be incorporated to the potential list of drugs and may serve as good genetic source for various modern breeding programs.

High prevalence of coronary artery calcification and increased risk for coronary artery disease in patients with Sheehan syndrome-A case-control study.

OBJECTIVE: Patients with Sheehan syndrome (SS) are predisposed to coronary artery disease (CAD) due to risk factors like abdominal obesity, dyslipidemia and chronic inflammation. In addition to estimate CAD risk enhancers like high sensitive C reactive protein (hsCRP), apolipoprotein B (ApoB) and lipoprotein A [Lp(a)], this study applies Framingham risk score (FRS) and coronary artery calcium (CAC) score to compute a 10-year probability of cardiovascular (CV) events in SS patients. DESIGN: Case-control study Sixty-three SS patients, on a stable hormonal replacement treatment except for growth hormone and 65 age, body mass index and parity-matched controls. MEASUREMENTS: Measurement of serum hsCRP, ApoB and Lp(a) and estimation of CAC with 16-row multislice computed tomography scanner. RESULTS: The concentrations of hsCRP, ApoB and Lp(a) were significantly higher in SS patients than in controls (p < .01). After calculating FRS, 95.2% of SS patients were classified as low risk, 4.8% as intermediate risk and all controls were classified as low risk for probable CV events. CAC was detected in 50.7% SS patients and 7.6% controls (p = .006). According to the CAC score, 26.9% SS patients were classified as at risk (CAC > 10) for incident CV events as against 1.6% controls. The mean Multi-Ethnic Study of Atherosclerosis (MESA) score was significantly higher in patients with SS than controls. CAC corelated significantly with fasting blood glucose (r = .316), ApoB (r = .549), LP(a) (r = .310) and FRS (r = .294). CONCLUSION: Significant number of asymptomatic SS patients have high coronary artery calcium score and are classified at risk for CAD.

Clinico-angiographic profile and procedural outcomes in patients undergoing percutaneous coronary interventions: The Srinagar registry.

BACKGROUND: This study was aimed at exploring the clinical profile, angiographic characteristics and procedural outcomes in patients undergoing PCI at our institute. METHODS: This prospective observational study included all consecutive patients who underwent PCI at our hospital between January 2014 and December 2015. Data including clinico-demographic profile, angiographic details and lesion characteristics were recorded in all patients. Procedural details including devices and drugs used, procedure related complications, and in-hospital outcomes of these patients were analysed. RESULTS: A total of 624 patients (mean age- 59.30±11.17years) with 84.8% males and 15.2% females were included in the study. Smoking and hypertension were the most common risk factors, present in 79.8% and 74.8% patients respectively. Diabetes mellitus, dyslipidemia, and obesity were observed in 24.5%, 26.1%, and 25.0% patients respectively. Anterior wall MI was the most common mode of presentation (32.1%). Single Vessel Disease (SVD) was most common angiographic pattern, observed in 50.3% patients; left anterior descending artery (LAD) was the most frequently involved vessel (65.9%); and type B lesions were most prevalent (52.3%). Most of the procedures were elective (61.4%) and femoral route was used in the majority (82.6%). Drug eluting stents were deployed in 99.1% of the cases. The overall procedural success rate was 93.6%. Procedural mortality was 1.0% and periprocedural complications occurred in 9.9% patients. CONCLUSION: This first prospective PCI registry from the state of Jammu & Kashmir provides an insight into the patterns of CAD among Kashmiri population, and highlights the spectrum of PCIs performed with their outcomes.

Prevalence and characterization of coronary artery disease in patients with symptomatic bradyarrhythmias requiring pacemaker implantation.

BACKGROUND: This study was conducted to assess the prevalence and characterization of CAD in high risk patients requiring pacemaker implantation for symptomatic bradyarrhythmias. METHODS: This study included 100 patients with symptomatic sinus node dysfunction or atrioventricular block, who were at high risk of CAD or had previously documented atherosclerotic vascular disease (ASCVD). Coronary angiography was performed before pacemaker implantation. CAD was defined as the presence of any degree of narrowing in at least one major coronary artery or its first order branch. Obstructive CAD was defined as ≥50% diameter stenosis. CAD was categorized as single vessel disease (SVD), double vessel disease (DVD), or triple vessel disease (TVD); and obstructive CAD in the arteries supplying the conduction system was sub-classified according to Mosseri's classification. RESULTS: Out of 100 patients (mean age 64.6±10.7 years), 45 (45%) had CAD. 29% patients had obstructive CAD while 16% had non-obstructive CAD. 53.3% patients had SVD, 15.6% had DVD and 31.1% had TVD. Among patients with obstructive CAD; Type I, II, III and IV coronary anatomies were present in 6.9%, 34.5%, 10.3% and 48.3% patients respectively. Presence of CAD significantly correlated with dyslipidemia (p=0.047), history of smoking (p=0.025), and family history of CAD (p=0.002). CONCLUSION: Angiographic CAD is observed in a substantial proportion of patients with symptomatic bradyarrhythmias and risk factors for CAD. It could be argued that such patients should undergo a coronary work-up before pacemaker implantation. Treatment of concomitant CAD is likely to improve the long term prognosis of these patients.

Lymphoma presenting as severe left ventricular systolic dysfunction: a case report.

Lymphoma involving the heart is rare. This is a case report on non-Hodgkin lymphoma where the patient presented for the first time with heart failure and severe left ventricular systolic dysfunction due to lymphoma infiltrating the heart muscle and had simultaneous bilateral involvement of kidneys. This type of presentation has never been described in world literature and is the first reported case.

Clinico-radiological profile of arrhythmogenic right ventricular dysplasia at a tertiary care center: Two year experience.

BACKGROUND: Arrythmogenic right ventricular dysplasia (ARVD/C) refers to fibro fatty infiltration replacement of ventricular myocardium especially that of right ventricle. The clinical presentation varies from asymptomatic state to ventricular tachycardia, heart failure and even sudden death. Diagnosis is established using modified ARVD/C taskforce criteria. Among all the various modalities of diagnosis, magnetic resonance imaging (MRI) gives most comprehensive evaluation of both morphological and functional abnormalities in this disease. MRI may not only obviate need for myocardial biopsy but also give insights into the nature of disease like presence of left ventricular myocardial involvement. We present our 2 years experience of ARVD/C patents who were admitted in our center and in whom diagnosis of ARVD/C was supported by excellent MR imaging. MATERIALS AND METHODS: This study was conducted by Department of Radiology and Cardiology SKIMS, a tertiary care center for a period of 2 years. Patients with suspected ARVD/C based on clinical, electrophysiological and echocardiographic findings were subjected to MR imaging. Patients were excluded if they had history metallic implants, claustrophobia or were uncooperative. In this study stress was laid on diagnostic role of MRI in ARVD/C. RESULTS: The median age at presentation was 31 years (range 21-43 years). 80% of patients were males. Most common clinical presentation was palpatations (40%). Syncope was present in 27% and heart failure in 13%. EKG suggestive of ARVD was seen in 87%. Echocardiographic features suggestive of ARVD/C was seen in all 15 patients. Family history of premature sudden death less than 35 years old was present in one patient only. MRI evidence classical for ARVD/C was seen in 80%. CONCLUSION: Demographic features and mode of presentation of our patients is consistent with what has been rest of the world. We performed MRI in all patients to increase the specificity of our diagnosis. MR imaging allows a three-dimensional evaluation of the right ventricle and provides the most important anatomic, functional, and morphologic criteria for diagnosis of ARVD/C within one single study. MR imaging appears to be the optimal imaging technique for detection and follow-up of clinically suspected ARVD/C.
