Spectrum of coronary angiographic findings in patients with ST Elevation Myocardial Infarction (STEMI) undergoing primary PCI in a tertiary care center of Nepal.

BACKGROUND: Even in developing countries like Nepal, prevalence of ST-elevation myocardial infarction has been shown to be increased with rise in prevalence of conventional risk factors like diabetes, Hypertension, smoking, dyslipidemia and obesity. Our aim is to retrospectively analyze for various risk factors and angiographic patterns of coronary artery disease in patients with ST-elevation myocardial infarction undergoing Primary Percutaneous Intervention. RESULTS: During the period of 1 year (January 2019 to December 2019), 816 patients presented to our ER with acute STEMI, among them 437 (53.6%) patients underwent primary PCI strategy and among them 22 (5.3%) patients were died. Thirty-six (4.4%) patients received thrombolysis, among them 5 (13.9%) patients were died while remaining 343 (42.0%) patients were managed conservatively and among them 20 (5.8%) were died. The mean age of patient who underwent primary PCI was 58.5±12.7 years range from 25 years to 99 years. Among them 55-75 years old 217 (49.6%) were highest in number followed by<55 years old 180 (41.2%). Males 318 (72.8%) were predominant. Among those who underwent primary PCI, hypertension 214 (49%) was the most common risk factor, followed by smoking 198 (45.3%), diabetes mellitus 123 (28.1%), dyslipidemia 53 (12.1%) and family history of premature coronary artery disease 18 (4.1%). Among those patients, 292 patients (66.8%) had single vessel disease, 99 patients (22.7%) had double vessel disease, 41 patients (9.3%) had triple vessel disease and 5 patients (1.1%) had non-significant coronary artery stenosis. Left anterior descending (53.3%) was the most frequently found culprit artery, followed by right coronary artery, left circumflex, ramus intermedius and left main artery. CONCLUSION: Fifty percent of patients presented with acute ST-elevation myocardial infarction and underwent primary PCI were between 55-75 years of age. Hypertension and smoking were the most common risk factors present in those patients. Single vessel disease was most prevalent with left anterior descending found to be the most commonly involved coronary artery followed by right coronary artery and left circumflex.

USG assisted and USG guided percutaneous renal biopsy at Nepal Medical College Teaching Hospital: a three and half years study.

A prospective study was carried out from 2009 to 2013 in the Department of Radiology and Imaging of Nepal Medical College and Teaching Hospital, Attarkhel, Jorpati, Kathmandu, Nepal, in which a total of 75 patients underwent percutaneous renal biopsy with a 16 or 18 gauge needles. This was done blindly by marking a site on the skin, or, whenever there was difficulty with the blind procedure, by direct real time USG guidance. In all cases, the marking in the skin was done by the radiologist and the biopsy was performed by the Nephrologist, with the aid of the radiologist in cases of real-time USG guided renal biopsy. This study was carried out to assess the safety and efficacy of the USG aided, and USG guided renal biopsy, to see for the types and severity of complications arising from renal biopsies to determine the optimal period of observation required after the procedure. All renal biopsies were performed after the patients were admitted to the hospital at least 1 day prior to the procedure. Coagulation profile was done in all patients prior to the procedure. All patients were kept under strict complete bed rest for 24 hours post procedure. The ages of the patients ranged between 14 years to 71 years, with 42 female and 33 male patients. A mean of 21.8 glomeruli was obtained in each specimen, with absent glomerular yield seen in only 3 patients. Minimal change disease was seen in 19 patients, being the most common histopathological diagnosis followed by a spectrum of others. The overall complication rate was 4% and all of these were self-limiting needing no other intervention, or management except for observation and bed rest. Late complications were not seen. Percutaneous renal biopsy with the help of USG is a safe and efficacious procedure with less chance of minor complications.

A study of risk factors of stroke in patients admitted in Manipal Teaching Hospital, Pokhara.

BACKGROUND: Stroke is usually end result of predisposing conditions that originated years before the ictus. Identification of its modifiable risk factors can help in planning preventive strategies. OBJECTIVE: To study the risk factors of stroke in adult patients. METHODS: A hospital based prospective cross sectional study was carried out in 160 stroke patients admitted in Manipal Teaching Hospital, Pokhara from November 2007- October 2010. Diagnosis of stroke was confirmed by CT scan of brain. Patients were then investigated for presence of conventional risk factors. The data was statistically analysed using Epi-Info. RESULTS: The mean age of stroke patients was 65.98 years +/- 10.69 with 126 (78.8%) of patients belonging to age group = 60 years. It afflicted higher percentage of males 104 (65%) than females 56 (35%). Analysis of stroke subtypes showed preponderance of haemorrhagic stroke in 85 (53.1%) as against infarction in 75 (46.9%) of cases. Other conventional modifiable risk factors were seen as follows: hypertension 98 (61.2 %), cigarette smoking 95 (59.4%), alcohol use 43 (26.9%), left ventricular hypertrophy 44 (27.5%), atrial fibrillation 37(23%), elevated triglyceride 37(23%), diabetes mellitus 15 (9.3%) and elevated total cholesterol 12 (7.5%). Multiple risk factors (=2) were seen in 122 (76.5 %) cases. CONCLUSIONS: The maximum occurrence of stroke was seen in patients > 60 years. Overall male preponderance and higher occurrence of haemorrhagic stroke was seen in our study. Significant risk factors in order of descending order were hypertension, cigarette smoking, left ventricular hypertrophy, alcohol use, atrial fibrillation and elevated triglycerides.

An unusual presentation of acute coronary syndrome.

Acute coronary syndrome in elderly can manifest with a variety of atypical presentation and may be associated with other comorbid conditions. We present an atypical presentation of ACS in an elderly left handed female presenting with sudden onset of slurred speech preceded by dizziness and vomiting. After through clinical examination and investigation she was managed as a case of non ST elevation myocardial infarction and ischaemic stroke.

Left ventricular noncompaction.

Left Ventricular Noncompaction (LVNC) is a genetic cardiac disease of emerging importance with a distinct clinical and pathophysiological presentation. The most common clinical manifestations include heart failure, arrhythmias and embolic events, and in children it may be associated with facial dysmorphisms and Wolff-Parkinson-White syndrome. The diagnosis of LVNC, however, is often missed, most often as a consequence of ignorance of the condition. Echocardiography is considered the reference standard for the diagnosis of LVNC. Prognosis remains poor for patients with impaired systolic left ventricular function, as treatment options are very limited. Because of the familial association of LVNC, first-degree relatives should be screened by Echocardiography.
