RESUMO
Coronary Artery Disease (CAD) is the most common type of heart disease. Assessment of coronary artery disease (CAD) is the starting point of determination of prognosis of patients presenting with clinical symptoms. ECG reflects the physiology of the myocardium during ischemia, while Coronary Angiography identifies vessel anatomy. In the present study, we aimed to correlate ECG changes with coronary angiographic findings along with prediction of number of vessels involved in patients of coronary artery disease. This study also intended to determine sensitivity and specificity of ECG for diagnosis of coronary artery disease using CAG as gold standard. MethodsThis cross-sectional study was carried out for a period of 2 years at Acharya Vinobha Bhave Rural Hospital, a tertiary rural health institute. 200 patients above 18 years of age who presented with or without symptoms and were willing for ECG and Angiography were included in study. Patients with valvular and congenital heart disease were excluded. Patients were divided into groups according to ECG changes and correlated with coronary angiography findings. ResultsIn the present study, the sensitivity and specificity of ECG to diagnose myocardial infarction or ischemia (AWMI / AWI, IWMI / IWI, and LWMI / LWI) ranged from 87.50% to 96.63% and 91.30% to 95.45%, respectively. Diagnostic accuracy of ECG to detect myocardial infarction or ischemia (AWMI / AWI, IWMI / IWI, and LWMI / LWI) ranged from 89.36% to 96.40%. ConclusionsECG is used as reliable tool for the diagnosis of coronary artery disease due to its high sensitivity and specificity, though CAG is the Gold Standard method for the diagnosis of CAD.
RESUMO
Introduction: Acute coronary syndrome (ACS) comprise the majority of hospital admissions and encompass a high risk of inhospital mortality. This study aimed to understand and assess the characteristics of hospitalized ACS patients, trends in theirmanagement as per evidence based medicine, and its impact on outcome. Materials & Methods: This was a prospective,observational study conducted at a tertiary care hospital in India during January 2018 to December 2018. All consecutive patientssuspected of ACS having age ≥ 18 years were admitted. During hospitalization, a case report form was filled out for patients withdiagnosis of ACS. It included data on demographic, clinical and electrocardiographic characteristics of the patients, diagnosis &treatment modalities. Treatment outcome was mentioned in terms of TIMI grading & in hospital complications. Results: A total of112 consecutive patients admitted in cardiac ICU were enrolled. Out of them 72 (64.28%) were males and 40 (35.72%) werefemales. Mean age of study cohort was 55.98±10.68 years. Most commonly associated conventional risk factors wereHypertension and diabetes [65 (58.04%) hypertensives and 33 (29.46%) diabetics]. Medical management was offered to 78(69.64%) whereas, 34 (30.36%) underwent PTCA or CABG. TIMI flow grading assessment done in 62 patients of which 1/3rdpatients showed TIMI grade 3.Conclusion: The present study showed higher ACS prevalence among patients who were in sixth toseventh decade of life, most commonly males, and associated with conventional risk factors, hypertension and diabetes.
