ABSTRACT
Introduction: Early detection of silent myocardial ischemia plays an important role in prevention of sudden cardiac death and acute myocardial infarction. The studies regarding the frequency of silent myocardial ischemia in diabetic patients having cardiovascular autonomic neuropathy are few so we planned this study to determine the frequency of silent myocardial ischemia among patients with diabetic cardiovascular autonomic neuropathy in our population
Objectives: To determine the frequency of silent myocardial ischemia in type 2 diabetic patients having cardiovascular autonomic neuropathy
Study Design: Cross-Sectional study
Place and Duration of Study: Medical Departments of Allied Hospital and Aziz Fatimah Hospital Faisalabad from 01-08-2013 to 31-01-2014
Methods: This study included 91 type 2 diabetic patients with cardiovascular autonomic neuropathy. All the patients had ECG done. Those who had normal ECG underwent ETT, to determine if there was any silent myocardial ischemia which was described as frequency distribution table. The data was collected on specially designed performa
Results: Total 91 patients were included in the study. Silent myocardial ischemia was present among 35 [38.5%] patients while 56 [61.5%] did not have silent myocardial ischemia. The mean age of the patients was 52.99 + 7.00 years [range 41-71years]. 57 [62.6%] patients were male and 34 [37.4%] patients were female. ECG was positive for ischemia among 25 [27.5%] patients and ETT was positive for ischemia among 10 [11%] patients
Conclusion: The frequency of the silent myocardial ischemia is high among patients with diabetic cardiovascular autonomic neuropathy, so every diabetic patient with cardiovascular autonomic neuropathy should be screened for ischemic heart disease
ABSTRACT
Introduction: Left ventricular hypertrophy, common in hypertension, is an adaptive state of the heart to increase in wall stress. LVH has important prognostic implications for patients with hypertension. In detection of LVH, Echocardiography is considered to be superior to electrocardiography in patients with hypertension
Objectives: To compare the findings of electrocardiography with echocardiography in terms of concurrence of results in the diagnosis of left ventricular hypertrophy
Study Design: Cross - sectional study
Place and Duration of Study: Medical Department of Allied Hospital and PINUM Faisalabad from 14-02-2014 to 13-08-2014
Material and Methods: A total of 88 patients were included in this study. After detailed history and examination, all patients had first ECG and then echocardiography
Results: Mean age of the patients was 50.85+6.3 year. Out of 88 cases, 55 patients [62.5%] were male while remaining 33 patients [37.5%] were female. Mean height of the patients was 1.69+0.10 meter, mean weight was 66.1+9.86 kg and mean BMI was 23.38+1.20. Out of 88 cases, 67 cases were positive on echocardiography and 39 cases were positive on electrocardiography [ECG]. Out of these 39 cases 37 cases were true positive, 2 cases were false positive
Conclusion: The results show that electrocardiogram has low sensitivity and low NPV for detecting LVH as compare to echocardiography. These findings are relevant for physiological LVH and should not be extrapolated to detection of hypertrophic cardiomyopathy. In clinical practice, echocardiography alone should be used to exclude LVH
