RESUMO
Background: The CONTROL (COversyl in Newly diagnosed stage-II & unconTROlled hypertensive patients triaL) was performed with an objective to evaluate the blood pressure (BP) lowering efficacy and tolerability of Perindopril 8mg in newly diagnosed stage II patients and uncontrolled hypertensive patients among Bangladeshi population. Methods: This was an open-label, observational, multi-center study conducted in consultation centers for out-patients located in different cities of Bangladesh. Adults, aged above 18 years with newly diagnosed stage-II hypertension or uncontrolled hypertension, were recruited. Patients were treated with Perindopril 4mg daily for first 1 week, afterwards uptitrated to Perindopril 8 mg daily and continued treatment for 12 weeks. Patients were followed-up at week-1, week-4, week-8 and week-12. Results: In total, 245 patients were enrolled. Among them, 88 were newly diagnosed stage-II (Group- I) and 157 were uncontrolled (Group-II) hypertensive patients. Male and female distribution was 57% and 43% respectively. Mean age of patients was 54.5 ±11.7 years. After 12 weeks treatment, there was a significant reduction in BP from baseline (p<0.001) in overall population as well as in Group I and in Group II. In overall population, the mean BP reduction was -31/-15 mmHg (from 163.7/96.8 mmHg to 132.4/81.7 mmHg. In Group I, the reduction was -33/-16 mmHg (from 166.5/98.2 mmHg to 133.4/82.0 mmHg) and in Group II, -30/-14 mmHg (from 159.3/ 95.6 mmHg to 129.1/81.6 mmHg). 10 patients (4.1%) had to discontinue the treatment due to adverse effects. Dry cough (2%) and hypotension (1.2%) were the main cause of discontinuation. Perindopril 8mg was well tolerated as indicated by the high proportion of physicians (81%) reporting ‘good’ to ‘excellent’ tolerability at week 12. Conclusion: This study suggests that Perindopril 8mg is effective and safe in the treatment of hypertension in Bangladeshi patients.
RESUMO
Coronary angiographic characteristics of fifty patients with type 2 diabetes mellitus and coronary artery disease (CAD) were compared with fifty non diabetic patients with CAD. Type 2 diabetic patients undergoing clinically indicated elective coronary angiography were individually matched with fifty non diabetic coronary artery disease patients for age, sex and major risk factors. No significant difference was present between the mean age, presenting complains and other coronary risk factors between the two groups. Severity and extent of coronary artery involvement was assessed by a coronary artery score (CAS) using the segmental distribution method for coronary artery lesions and morphometric analysis of atherosclerotic lesion was done. Type 2 diabetic patients had a higher CAS (11.74+/-5.04 vs 8.72+/-4.87; P<0.001) as compared to the non-diabetic patients. Multivessel disease were more prevalent in both the groups (82% vs 68%; P>0.05) but diabetic patients had significantly higher number of triple vessel disease (58% vs. 38%; P<0.001). Normal coronary arteries and single vessel disease were more prevalent in non-diabetic patients (32% vs. 18%; P<0.05). As compared to non-diabetic group diabetic patients had a higher total number of diseased vessels (78.66% vs. 68%; P<0.01), a higher lesion per patient ratio (3.94+/-1.80 vs 3+/-1.67:P<0.001) and more proximal lesions (40.83% vs. 34.70%; P>.05) though not statistically significant. Morphometric analysis of coronary artery lesions revealed that diabetic patients had significantly higher number of multiple irregularity lesions (24.37% vs. 15.33%; P<0.01) and lesions were more obstructive (lesion involving 70-90% of coronary lumen: 70.53.% vs. 57.33%; P<0.05). Though there was no significant difference between the systolic left ventricular function between the two groups but significant higher regional wall motion abnormality was found more in diabetic patients (76%vs 62%; P<0.01). So type 2 diabetic patients had more severe and extensive atherosclerotic lesion in their coronary arteries than the matched non diabetic control on coronary angiography suggesting an independent effect of diabetic mellitus on atherosclerotic process specially in our population.
