Assessment of Coronary Microvascular Diastolic Transit Time (CMDTT) and its Correlation with Myocardial Dysfunction
Abstract: Aim: We assessed the CMDTT in patients with coronary atherosclerosis risk factors such as Diabetes Mellitus, Hypertension and smoking to those without risk factors and correlated with insipient LV myocardial dysfunction. Methods: 104 patients (54 females, 50 males) were included. 52 patients in each risk factor group such as DM, HTN, smoking and 52 were in control group without any risk factors. Results: The mean age of the subjects was 53.8 +/- 11.04 years. Mean CMDTT in subjects without any risk factor was 2.31±0.25 seconds, 2.51±0.59 seconds in subjects with risk factors (p<0.05). Conclusion: Presence of increased CMDTT in patients with risk factors for endothelial dysfunction of main vessels and is predictor of onset of left ventricular dysfunction well before any non invasive testing modality for assessment of left ventricular muscle dysfunction.
