ABSTRACT
AIM: To investigate the effects of internal change of serum insulin and plasma glucose levels on serum free fatty acid (FFA) concentrations after glucose loading. METHODS: Serum insulin, plasma glucose and FFA concentrations were measured simultaneously in 234 essential hypertension patients who were undergoing oral glucose tolerance test (OGTT) [ including 20 cases with 2 type diabetes mellitus (DM), 74 impaired glucose tolerance (IGT), 140 normal glucose tolerance (NGT); 98 males, 136 females]. RESULTS: Fasting serum FFA concentration (?mol/L) in DM ((1 048.47)?481.6) was higher than that in IGT (760.1?332.1) (P
ABSTRACT
Objective:To investigate the relationship between the left ventricular morphology, systolic function and the severity of the coronary artery lesions. Methods:A total of 589 consecutively admitted patients were studied retrospectively. All patients suspected of coronary artery disease underwent a selective coronary angiography and a survey of left ventricular ejection fraction (EF) during the hospitalization. Results:A significant correlation between the severity of the coronary artery lesions and the EF, FS, LADD, LADS, LVDS and LVDD was found through the Bivariate Correlation analysis ( P
ABSTRACT
Objective: To investigate the findings of coronary artery angiography in coronary artery disease patients with diabetes mellitus. Methods: The angiographic fingings of 153 coronary artery disease patients from 1995 to 1997 were reviewed. Among them, 33 were diabetic,23 were impaired glucose tolerance(IGT) and 97 were nondiabetic patients. Results: The age, sex, hypertension, hypercholesterolemia, smoking and the rate of myocardial infarction were the same among 3 groups. But the 2 vessel and 3 vessel disease were more frequent in diabetic group(66.7% ,30.3%) than in nondiabetic group (26.8%,19 6%). Two vessel disease were more frequent in diabetic group(66.7%) than in IGT group (13.1%). Single vessel disease were less frequent in diabetic group(3.0%) than in IGT group(52.2%)and nondiabetic group(53.6%)( P
ABSTRACT
Objective To evaluate the efficacy of primary percutaneous coronary intervention (PCI) for acute myocardial infarction. Methods 63 patients with acute myocardial infarction were treated by primary PCI within 12 hour from onset and were followed up for one to fourteen months. Results Procedure was successed in 61 patients (96.8%). Three patients received only primary angioplasty and 58 patients received stent implantation. All of them gained TIMI Ⅲ grade perfusion flow. Non-perfusion flow occurred in five patients but their flows were improved by intracoronary urokinase infusion. Ventricular tachycardia and fibrillation happened in five patients, and were converted to sinus rhythm by defibrillation in four and one died. Two of the five patients complicated with cardiogenic shock, with one died on 1st day and the other on 4th day after successful PCI, respectively. Main cardiac events occurred in five patients (17%) during follow-up with two sudden death , one reinfarction and repeated PCI, one received selective CABG and one PCI due to intrastent restenosis. Conclusions Primary PCI could provide higher successful rate of reperfusion with low hospital mortality and good short-term prognosis.
ABSTRACT
Objective To evaluate the determinants of successful recanalization of chronic coronary arterial total occlusion(CTO) by percutaneous coronary intervention(PCI) as well as the effect of the recanalization on the prognosis of the patients. Methods Fifty-two patients with CTO were treated by PCI. 30 patients (duration more than one month) were successfully recanalized with stent implantation. Their clinical features and prognosis were compared with those without successful recanalization. Results Compared with patients without successful recanalization, patients with successful recanalization had a higher incidence of hypertension(53% vs 23%, P
