Publication Association of Cardiovascular Risk Factors and Coronary Artery Lesion Among Coronary Artery Disease Patients(Kathmandu University, 2014) Koju, R; Humagain, S; Khanal, KABSTRACT Background Coronary artery disease (CAD) is associated with the numbers of risk factors causing coronary atherosclerosis. Coronary artery stenosis is mostly caused by coronary atherosclerosis. Objective This study aims to analyze the association between coronary artery stenosis and cardiovascular risk factors. Methods An observational study was conducted among CAD patients. The diagnostic coronary angiogram was performed from femoral approach using standard catheters and techniques to find out any abnormalities. Result A total 73 patients (44 male and 29 female) with coronary artery disease undergoing diagnostic coronary angiography was included with the documented cardiovascular risk factors. The coronary stenosis was found in 40 patients on the basis of stenosis grading. Among the established cardiovascular risk factors, sex, diabetes mellitus and smokers show are significantly associated with coronary stenosis among CAD patients. The present study shows the significant association of coronary stenosis among male CAD patients (OR 2.47; CI 0.94 – 6.48, p <0.05) and similar association has been observed in diabetes mellitus (OR 3.32; CI 1.12 – 9.84, p <0.05) and smoking (OR 4.10; CI 1.45 – 11.61, p <0.01). Conclusion The prevalence of CAD is increased with numbers of presence of cardiovascular risk factors. Male gender, diabetes mellitus and smoking are significantly associated with coronary stenosis among CAD patients. However, hypertension and dyslipidemia are comparable between coronary stenosis and no significant stenosis group.

Difference in response to antihypertensive medication depending on ethnic group is well recognized. There is very few data regarding this difference in the South Asian population especially from Nepal. Objective The aim of this study is to find out which antihypertensive medication has better efficacy in our population. Method One seventy two newly diagnosed hypertensive patients who presented to cardiology OPD were included. Blood Pressure (BP) was recorded in both arms at least three times. Patients were counseled for lifestyle and dietary modification and were prescribed one of the three drugs Hydrochlorthiazide 25 mg or Amlodipine 5 mg or Enalapril 5 mg. Patients were called back in 4-6 weeks time and Blood Pressure was recorded in similar manner. Result Out of 172 patients, 97 were male and 75 female. The mean age was 55.49±1.03 years. Mean Systolic BP before treatment was 156.2±10.6 mm of Hg and Mean Diastolic BP before treatment was 100.5 ±6.8 with no statistically significant difference among different groups. However Systolic BP reduction was 14.6 ±5.1, 21.9±5.9 and 21.8±7.4 by Hydrochlorthiazide , Amlodipine and Enalapril respectively. Diastolic BP reduction was 8.8±2.5, 14.2±2.8 and 14.3±2.9 by Hydrochlorthiazide, Amlodipine and Enalapril respectively. Conclusion Amlodipine and Enalapril are equally effective in controlling BP in our population. Hydrochlorthiazide is less effective than both Amlodipine and Enalapril. KEY WORDS Amlodipine, antihypertensive drugs, efficacy, enalapril, hydrochlorthiazide.Publication Neonatal Arrhythmia(Kathmandu University, 2020) Joshi, A; Humagain, SABSTRACT Arrhythmias are seldom observed in the newborn period and rarely lead to serious consequences. Because they may be a continuation of fetal arrhythmias, newborn arrhythmias are different from those occurring at later ages. Here we describe a case of a newborn presented with tachycardia at birth. A female baby of 1950 grams born by emergency cesarean section for fetal distress at 36 weeks of gestation. Fetal tachycardia of 251 bpm was detected prenatally. Electrocardiography showed supraventricular tachycardia (SVT). Hematological and biochemical tests done were within normal limits. Echocardiography revealed normal anatomy with severe tachycardia, dilated chambers with moderate to severe TR with moderately reduced ventricle function. For persisting SVT intravenous adenosine was administered with no significant decrease in heart rate, then continuous intravenous amiodarone infusion was started resulting in a transient decrease in heart rate, however again increased, hence baby was started on intravenous digoxin which responded well. Repeated echocardiography showed normal cardiac chambers and function. Baby was discharged on maintenance oral digoxin and was gradually weaned and stopped after 12 months of age. Neonatal arrhythmias is not an uncommon condition in newborns, however it should be early recognized and evaluated for a better outcome of the baby. Although the frequency of arrhythmias in the newborn period is not high, SVT are the most frequently observed arrhythmias in this period. KEY WORDS Fetal tachycardia, Neonatal arrhythmias, Supraventricular tachycardiaPublication Prevalence and Associated Risk Factors of Hypertension Among People Aged 50 years and more in Banepa Municipality, Nepal(Kathmandu University, 2012) Manandhar, K; Koju, R; Sinha, NP; Humagain, SABSTRACT Background Hypertension is a cardiovascular disorder rapidly emerging as a major public health problem in developing countries and is the most widely recognized modifiable risk factor for cardiovascular diseases. Objective The objective of this study was to find out the prevalence and associated risk factors with hypertension among people aged 50 years and more in Banepa Municipality, Kavre, Nepal. Methods It is a cross- sectional, population based study which was carried out in Banepa Municipality from May 15 to June 15, 2009. Among total 11 wards of Banepa municipally, wards number 1, 3, 5, 6, 7, and 10 were selected by using Simple Random Sampling Technique and 405 subjects of people aged 50 years and more were selected for study from the selected wards by using Cluster Sampling. The structured interview method was used for collection of data. Mercury sphygmomanometers with standard cuff were used to measure the indirect auscultatory arterial blood pressure. Two consecutive blood pressure readings were taken and average of them was calculated to determine single value of blood pressure. Results The prevalence of hypertension was 44.9 percent (47.75% in male and 42.73% in females). Among them, only 32.9 percent (60/182) were previously diagnosed as hypertension. The higher proportion of hypertensive cases were in age > 65 years (55.49%) than in the age group < 65 years (36.32%). The prevalence of hypertension was seen positively associated with non vegetarian eating habits, alcohol consumption, and > 25 Body max index. Taking green leafy vegetable at least once a week was negatively associated with the prevalence of the hypertension. Conclusion These findings provide important information on the prevalence, associated factors of hypertension in Banepa Municipality. Effective public health measures and strategies are needed to improve prevention, diagnosis and access to treatment of these 50 years and above population. KEY WORDS Associated risk factors, cardiovascular disease, hypertension, prevalencePublication Radiation Exposure to the Patient During Diagnostic Coronary Angiogram at Dhulikhel Hospital(Kathmandu university, 2015) Humagain, S; Maharjan, R; Koju, RABSTRACT Background Radiation is a necessary evil in Coronary Angiogram. The Interventional Cardiology procedure provides huge benefit to the patient but at the cost of radiation. There is evidence of cumulative effect of radiation. Therefore it is essential to keep the radiation dose as minimum as possible. Objective The aim of this study is to find out radiation exposed to the patient undergoing diagnostic coronary angiogram. Method A retrospective study was done. Those patients who underwent diagnostic coronary angiogram were selected for the study. There were total of 166 patients. Radiation exposure in terms of fluoroscopy time in minute and dose area product (DAP) in Gy.cm2 was recorded. Result Out 166 patients 92 were male and 74 female. Age range was from 39 to 79 years with mean age 58.13±9.14. Amount of contrast used was in range of 30 to 100 ml with mean of 45.54±14.06. Range of fluoroscopy time was 2.60 to 37.00 minutes with mean 11.38±6.80. Mean fluoroscopy time in male was 10.92±5.82 minutes and in females it was 11.92±7.68 minutes, with p 0.331. The range of DAP was 11.00 Gy.cm2 to 106.00 Gy.cm2 with mean 40.73±23.58 Gy.cm2. The mean DAP in male and female was 38.77±23.26 Gy.cm2 and 43.16±23.90 Gy.cm2 respectively with p 0.234. Conclusion From this study we can conclude that the radiation exposure to our patient undergoing coronary angiogram is similar to the international values in terms DAP but more in terms of fluoroscopy time. When males and females compared there is no difference. KEY WORDS Coronary angiogram, dose area product (DAP), fluoroscopy time, radiation
