Use of Statin and Target Low-density lipoprotein cholesterol attainment among post-ST elevation myocardial infarction patients in Shahid Gangalal National Heart Centre, Kathmandu, Nepal.

BACKGROUND: and objective: Lipid-lowering is an important intervention to reduce cardiovascular morbidity and mortality in the secondary prevention of STEMI. There is no study to analyze the use of statin and LDL-C treatment target attainment among STEMI patients in Nepal. This study aims to assess the use of statin and LDL-C treatment target attainment among STEMI patients. METHODS: It was a prospective observational single-center study conducted at the Shahid Gangalal National Heart Centre, Kathmandu, Nepal outpatient department. An outpatient department-based survey was conducted among STEMI patients who have lipid profile levels at the time of admission for STEMI and after 4-13 weeks of the index event. Lipid profile levels, diagnosis, and risk factors were collected during the outpatient follow-up. RESULTS: Our study included 280 post-STEMI patients; the mean age was 57.5±11.7 years with the majority being male. The mean duration of follow-up was 6.7 ± 0.1 weeks. Rosuvastatin was the preferred statin with 82.1%. The most common dose of statin used was Rosuvastatin 20mg (70%), followed by Atorvastatin 40mg (12.5%). LDL-C levels of <1.4mmol/l were achieved in 44.6% of cases and LDL levels of <1.8mmol/l in 71.8% of cases. In 36.8% of the study population, there was a greater than 50% decline in LDL-C levels. Diabetic patients (55.1% and 83.1%) only have the significant achievement of LDL goal of both <1.4mmol/l and <1.8mmol/l respectively, when compared to those without diabetes (44.9% and 16.9%). CONCLUSIONS: Most of the post-STEMI patients were treated with high doses of statins and achieved the target LDL-C levels.

Congenital unilateral absence of right pulmonary artery with VSD and wide aortopulmonary window in an adult patient: a case report.

Unilateral absence of pulmonary artery (UAPA) is a very rare condition, with an estimated prevalence of 1 in 200,000 population, which is commonly associated with various cardiovascular anomalies or can occur in an isolated manner. Isolated cases survive to adulthood and remain asymptomatic, but they may frequently experience hemoptysis, repeated infections, or symptoms like dyspnea and chest pain. Due to the rarity of the disorder and its ambiguous appearance, diagnosis can be very challenging. Case presentation: We present a case of a 28-year-old male who visited our center with the diagnosis of ventricular septal defect with Eisenmenger syndrome elsewhere for further evaluation and was found to have right-sided UAPA with ipsilateral pulmonary hypoplasia and some associated cardiac anomalies. Clinical discussion: Discussions are held regarding typical chest radiograph findings, diagnostic methods, and possible therapies. Conclusion: Physicians should be aware of UAPA, which might go undiagnosed for several years despite regular medical care and can show up later in life, causing chronic respiratory symptoms along with Eisenmenger syndrome and ventricular septal defect like in our case.

Patterns of Perception of Cardiac Symptoms by Patients Presenting with ST-Segment Elevation Myocardial Infarction and their Knowledge of Coronay Artery Disease Risk Factors.

BACKGROUND: Proper knowledge regarding Coronary Artery Disease and their risk factors is essential for the early recognition of the disease and its presentation. This study was conducted to identify pattern of clinical symptoms and knowledge regarding Coronary Artery Disease risk factors among ST-Elevation myocardial infarction (STEMI) patients. METHODS: This cross-sectional, observational study was conducted among 340 ST-Elevation myocardial infarction patients in the inpatient Cardiology Department of Shahid Gangalal National Heart Centre Nepal, from November 2020 to February 2021. Baseline clinical characteristics, knowledge regarding Coronary Artery Disease risk factors, patterns of symptoms, and prehospital delay were collected and evaluated. RESULTS: In our study, 299 (87.9%) had typical ischemic chest pain during the symptom onset, however, only 81 (23.8%) perceived chest pain as cardiac disease, and 311 (91.5%) of the patients presented to the nearby health care center within the recommended time of less than 12 hours for the reperfusion therapy of ST-Elevation myocardial infarction. Perception of symptoms as a cardiac origin and typical chest pain were not significantly associated with earlier presentation. Also, the typical chest pain was not significantly associated with the perception of the symptom as a cardiac origin. The history of Coronary Artery Disease was considered as a Coronary Artery Disease risk factor by 184(54.1%) of the study population and 137(40.3%), 132(38.8%), 110(32.4%), 105(30.9%) and 71(20.9%) considered hypertension, smoking, age, obesity, and diabetes mellitus as a Coronary Artery Disease risk factor respectively. CONCLUSIONS: Though most patients presented with typical chest pain, identification of the chest pain as a cardiac origin and the awareness of the Coronary Artery Disease risk factors was low.

Cardiovascular disease risk factors distribution and clustering across different geographic levels in Nepal.

BACKGROUND: In an effort to reduce the burgeoning problem of cardiovascular diseases (CVD), it is imperative to understand the variation of risk factors across different geographic regions. This study aims to shed light on examining the leading risk factors of CVD and it's clustering across Nepal. METHODS: Data from a nationally representative survey were analyzed to estimate the distribution of four major risk factors (high blood pressure, overweight, obesity, and smoking) of cardiovascular diseases. Similarly, this study also assessed the intra-cluster correlation coefficients (ICCs) of CVD risk factors at the household, community (urban/rural), district, and province level. RESULTS: This study included 14 418 adult population with age of 15 years and above of which 41.7% were male and 58.3% were female. Higher prevalence of all four CVD risk factors was found in the richest quintile, people living in hilly region, most noticeably among residents of metropolitan city and in Gandaki, Bagmati, and Province 1. The ICC decreased as the socio-geographic clustering units decreased in size from province, district, and household level clustering. The ICC was highest at province level for "province 1" for raised blood pressure than other provinces. CONCLUSIONS: Risk factors of CVD in Nepal are concentrated prominent in highly urbanized areas and ICC is low as the level of geography decreased from province, district, and household. The findings can be applied in directing prevention activities at different levels to mitigate the higher burden of risk factors of CVD in Nepal.

Feasibility and Safety of Distal Radial Artery Access in Anatomical Snuffbox for Coronary Angiography and Coronary Intervention.

BACKGROUND: There is limited data on feasibility and safety of coronary interventions performed using radial artery at anatomical snuffbox as vascular access point in South Asian region. Our study attempts to evaluate the feasibility and safety of coronary angiography and percutaneous coronary intervention using transradial access at anatomical snuffbox. METHODS: Transradial access at anatomical snuffbox was attempted in 128 consecutive patients, who were planned for coronary angiography and/or percutaneous coronary intervention. Success in vascular access, completion of planned procedure and complications encountered, including patency of radial artery after the procedure, were investigated. RESULTS: A total of 128 patients (76 males [59.4%]; 52 females [40.6%]) between 44-78 years of age (mean age, 59.0 +/- 10.2 years) were included in the study. Distal radial artery puncture and sheath placement was successful in all patients however planned procedure was completed in 126 (98.4%) patients. Total 90 coronary angiographies and 36 percutaneous coronary interventions were performed of which five were primary percutaneous coronary intervention. We encountered brachial artery spasm among two patient (1.5%) and significant pain and swelling among three patients (2.3%). No bleeding complication, numbness or parasthesia were observed on follow-up. Patients had average pain rating of 2.4+/- 1.1 in visual analogue pain rating scale. There were no instances of radial artery occlusion after the procedure. CONCLUSIONS: Distal radial artery, at anatomical snuffbox, is a safe and feasible alternative vascular access site for coronary angiography and percutaneous coronary intervention.
