Effect of NPC1L1 and HMGCR Genetic Variants With Premature Triple-Vessel Coronary Disease

Background: Both Niemann-Pick C1-like 1 (NPC1L1) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) play a key role on dyslipidaemia. We aim to evaluate whether NPC1L1 and HMGCR genetic variants are associated with susceptibility of premature triple-vessel disease (PTVD).Methods: Four single-nucleotide polymorphisms (SNPs) (rs11763759, rs4720470, rs2072183, and rs2073547) of NPC1L1; and three SNPs (rs12916, rs2303151, and rs4629571) of HMGCR were genotyped in 872 PTVD patients (males ≤ 50 years old and females ≤ 60 years old), and 401 healthy controls.Results: After adjusting for age and sex, rs12916 of HMGCR was associated with the risk of PTVD in dominance model [odds ratio (OR) = 1.68, 95% confidence intervals (CI): 1.29–2.18, P < 0.001], recessive model (OR = 1.43, 95% CI: 1.08–1.90, P = 0.013) and codominant model (OR = 1.38, 95% CI: 1.17–1.63, P < 0.001); meanwhile, rs4720470 of NPC1L1 was related to increased risk of PTVD in recessive model (OR = 1.74, 95% CI: 1.14–2.74, P = 0.013). Patients who carried both variant rs4720470 and rs12916 also had the risk of PTVD (P < 0.001); however, there were no correlation between these SNPs and the SNYTAX score (all P > 0.05).Conclusions: This is the first report that rs4720470 is a novel polymorphism of the NPC1L1 gene associated with PTVD, and rs12916 of HMGCR gene appears to be a strong genetic marker of PTVD. Our study may improve the early warning, therapeutic strategies and drug development of PTVD.

Extensive triple vessel coronary artery disease in a young male with juvenile idiopathic arthritis

ABSTRACT The risk of cardiovascular disease in patients with chronic inflammatory joint conditions is substantially increased compared to the general population. We present a case of a 27-year-old male with a chronic history of juvenile idiopathic arthritis (JIA) who presented with denovo acutely decompensated chronic heart failure. He had no traditional risk factors for atherosclerotic cardiovascular disease (ASCVD). However, during his workup for dilated cardiomyopathy, he was found to have extensive triple vessel disease on coronary artery angiography, and this was subsequently thought to be the most likely aetiology for the dilated cardiomyopathy despite being of young age. The chronic JIA was identified as the principal risk factor for the ischaemic cardiomyopathy. Clinicians treating patients with rheumatological conditions should routinely screen for ASCVD, despite the absence of traditional cardiovascular risk factors.

Association between Endogenous Sex Hormones and Coronary Artery Disease in Postmenopausal Women

Background Incidence of coronary artery disease (CAD) increases significantly in postmenopausal women, which is assumed to be an imbalance between serum androgen and estrogen levels. However, studies assessing serum sex hormones and CAD are few and have shown conflicting results. Objective To compare serum sex hormone levels and traditional risk factors among postmenopausal women with angiographically proven CAD and without CAD. Method The study included consecutive postmenopausal women undergoing coronary angiography in our institute from May 2016 to June 2017. The clinical and coronary angiographic data and traditional risk factors were assessed. Fasting serum levels of estradiol (E2), testosterone (T), sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEA-S), and insulin were measured. Results A total of 121 postmenopausal women were included in the study; 69 were CAD and 52 without CAD. Single-vessel disease was most common (55.1%), followed by double-vessel disease (24.6%) and triple-vessel disease (20.3%). Women with CAD had significantly lower estradiol/testosterone (E2/T) ratio (3.7 ± 2.6 vs. 5.4 ± 4.2, p = 0.008) compared with non-CAD group. SHBG, DHEA-S, and insulin levels were similar in CAD and non-CAD groups. The serum level of estradiol predicted the E2/T ratio (r = 0.316, p < 0.001) and positively associated with DHEA (r = 0.181, p = 0.047). Testosterone was negatively associated with E2/T ratio (r = – 0.682, p < 0.001). There was no significant correlation of estrogen, testosterone, or E2/T ratio to lipid profile (total cholesterol, HDL, LDL) in women with CAD. Conclusion E2/T ratio was significantly lowered in postmenopausal women with CAD. E2/T ratio may be a used a predictor of CAD in postmenopausal women

Assess the Patient’s Perspicacity Regarding Triple Vessel Disease and Its Management

Background: The single greatest killer in both females and males globally is cardiovascular disease. Coronary artery disease, commonly known as ischemic heart disease, is described as “impairment of heart function induced by obstructive alterations in the coronary circulation to the heart, caused by inadequate blood flow to the heart relative to its needs.” There are 4.5 million persons in India who suffer from coronary artery disease. Objective: In this study planned to determine the patient’s perception regarding triple vessel disease and its management and to associate the demographic variable with the patient’s perception regarding triple vessel disease and its management. Methodology: It is a descriptive research design used in this research study conducted on patients are having triple vessel disease. The purposive sampling technique is used to select samples for analysis. This research study included 45 patients of a selected hospital in Wardha district. Patients must select according to requirements for inclusion and exclusion. For this study, patients who had triple vessel disease would mainly take. Expected Results: The patients are having good perception or may be having bad perception. Conclusion: The conclusion will be drawn from the results. The patient’s will be having good or bad perception regarding triple vessel disease and its management.

Risk factors for revascularization and in-stent restenosis in patients with triple-vessel disease after second-generation drug-eluting stent implantation: a retrospective analysis

Objectives Coronary artery disease (CAD) is a common cardiac disease with high morbidity and mortality, and triple-vessel disease (TVD) is a severe type of CAD. This study investigated risk factors for revascularization and in-stent restenosis (ISR) in TVD patients who underwent second-generation drug-eluting stent implantation. Methods A retrospective clinical study was conducted, and 246 triple-vessel disease (TVD) patients with 373 vessels after second-generation drug-eluting stent (DES) implantation who received follow-up coronary angiography (CAG) were consequently enrolled. According to the follow-up angiography, patients were categorized into the revascularization group and nonrevascularization group as well as the in-stent restenosis (ISR) group and non-ISR group. Univariate and multivariate logistic regression analyses were used to identify risk factors for revascularization and ISR. Receiver operating characteristic (ROC) curve with area under the curve (AUC) analysis was performed to assess the predictive power of these risk factors. Results In the median follow-up period of 28.0 (14.0, 56.0) months, 142 TVD patients (57.7%) with 168 vessels underwent revascularization, and ISR occurred in 43 TVD patients (17.5%) with 47 vessels after second-generation DES implantation. Compared to the nonrevascularization group, the revascularization group presented with an increased rate of current smoking and higher levels of TC, LDL-C, HDL-C, non-HDL-c, ApoB, neutrophils, and Hs-CRP as well as a longer follow-up of months but with a lower level of HDL-C. In addition, patients in the ISR group had an older age, longer follow-up (months) and elevated rates of current smoking and stage 4–5 chronic kidney disease (CKD4-5). In multivariate analysis, current smoking and higher non-HDL-c were independent risk factors for revascularization. In addition, older age, current smoking and CKD4-5 were considered independent risk factors for ISR. Importantly, the receiver operating characteristic curve showed that non-HDL-C and age displayed predictive power for revascularization and ISR, respectively. Conclusion Current smoking is an independent risk factor for both revascularization and in-stent restenosis. Higher non-HDL-c is independently related to revascularization; moreover, increased age and CKD4-5 are potential risk factors for ISR in TVD patients after second-generation drug-eluting stent implantation.

Histopathological array of cardiac lesions: An autopsy based study in a tertiary care centre

Cardiac lesions are responsible for approximately 60-70% of sudden deaths. Histopathological examination of heart on autopsy plays an essential role in determining the cause of death.The present study was conducted to analyse histopathological spectrum of various cardiac lesions in autopsy specimens.This retrospective randomized study was conducted in the Department of Pathology, Pt. B. D. Sharma, PGIMS, Rohtak, Haryana. A total of 1152 autopsies were analysed, irrespective of cause of death. Among them heart was included in 1062 autopsies, out of which 62 were autolysed. Hence, 1000 specimen of whole heart were included in our study. A detailed gross and microscopic examination was done and histopathological findings were correlated clinically.Atherosclerosis was the most common cardiac lesion seen in 610 out of 1000 autopsied heart (61%), followed by ischaemic heart disease in 346 cases (34.6%). 27 cases had pericarditis, 23 cases revealed myocardial hypertrophy, 16 cases showed myocarditis, 11 cases had ventricular haemorrhage, 8 cases revealed changes of electrocution, 7 cases had tuberculosis, 6 cases had calcification of valve and 4 cases had metastasis from carcinoma. One case each of infective endocarditis, rheumatic heart disease and aortitis were also noted. The cause of death was not identified in 304 cases. Left anterior descending artery was most frequently involved vessels (35.02%) followed by left circumflex artery (33.41%) then right coronary artery (31.57%). Out of three major vessels 16.24% had single vessel involvement whereas 32.14% & 51.62% cases had two vessels and three vessels involvement respectively. Ischemic heart disease with coronary artery atherosclerosis was found to be the leading cause of death with triple vessel disease as the most common pattern of involvement.

Coronary Artery Bypass Grafting in a Patient With Situs Inversus Totalis: A Case Report

Background: Coronary artery bypass grafting in situs inversus totalis patients has been seldom reported in the literature. Case presentation: A 76-year-old woman visited our hospital for chest pain and dyspnea that had started about 5 years earlier. Coronary angiography revealed triple-vessel disease, and computed tomography showed situs inversus totalis. Coronary artery bypass grafting was performed. In this case, the main operating surgeon stood on the right side of the patient until cardiopulmonary bypass was established and then switched positions to the left side of the patient for anastomosis.Conclusion: CABG was successfully completed in a patient with situs inversus totalis. The position shift helped improve the safety and ease of the surgery.

Euglycemic diabetic ketoacidosis - a rare side effect of sodium-glucose co-transporter-2 inhibitor in a patient of type 2 diabetes mellitus with left ventricular dysfunction: a case report

A 42 year old female with type 2 diabetes mellitus (T2DM), presented with angina on exertion and left ventricular (LV) dysfunction (global LV ejection fraction (EF)=26%). Patient was subjected to coronary angiography which revealed triple vessel disease. Patient was started on usual standard of care heart failure (HF) medications, including sodium-glucose co-transporter-2 (SGLT-2) inhibitor dapagliflozin which is promising new class of drug for treating T2DM and HF. Patient was advised myocardial revascularization in form of percutaneous transluminal coronary angioplasty (PTCA). Post angioplasty patient developed metabolic acidosis (high anion gap with normal lactate and increased ketone levels). Patient was diagnosed as case of euglycemic diabetic ketoacidosis (DKA) and patient was treated by volume resuscitation and insulin infusion.

Serum Vitamin D Level in Patients Undergoing Coronary Artery Catheterization

Background: Vitamin D deficiency may be a risk factor for coronary artery disease (CAD). We aimed to measure the prevalence of vitamin D deficiency in CAD and its association with severity of angiographic proven CAD. Methods: This prospective, cross-sectional study included 106 consecutive patients who were admitted for typical angina and had signs of myocardial injury (ECG findings and/ or elevated troponin I or CK-MB) and who underwent coronary angiography at the university hospital of BPKIHS from August 2020 to April 2021. Patients were categorized into angiographic proven CAD group and angiographic normal coronary artery group. Serum vitamin D level was classified as normal (≥ 30 ng/ml) and deficiency (< 30 ng/ml). Results: Out of 106 patients, 78 patients (73.6%) had vitamin D deficiency and 28 (26.4%) had normal vitamin D level (p = 0.39). Vitamin D level (mean ± SD) in patients with angiographic normal coronary artery and angiographic proven CAD were 25.94 ± 11.63 ng/ml and 26.07 ± 12.90 ng/ml respectively (p = 0.97). Prevalence of vitamin D deficiency was 75.0% and 64.3% in significant CAD group and normal coronary artery group respectively (p = 0.39). Similarly, frequency of vitamin D deficiency were 68.6%, 78.3% and 88.90% in single, double, and triple vessel disease respectively (p = 0.21). The vitamin D level (mean ± SD) in single, double and triple vessel disease were 27.31 ± 14.02 ng/ml, 25.69 ± 12.72 ng/ml, 23.08 ± 9.45 ng/ml respectively. Conclusion: The prevalence of vitamin D deficiency in both angiographic normal coronary artery and angiographic proven CAD were high but comparable. There was no association of vitamin D deficiency with severity of angiographic proven CAD.
