Résumé

A quadruple blind randomized cross-over study evaluated the therapeutic efficacy of twice a day long acting sustained release isosorbide dinitrate (SRISDN) in comparison with 4 times daily of the short acting isosorbide dinitrate in 18 patients with stable angina pectoris (NYHA class II-III) with a positive exercise treadmill test. The antianginal effect of sustained release isosorbide dinitrate (SRISDN) (exercise duration 472.61 +/- 112.49 sec and anginal episodes per week (1.33 +/- 1.18) was not significantly different (p less than 0.05) when compared to conventional isosorbide dinitrate (exercise duration 468.33 +/- 135.28 sec and anginal episodes per week 1.55 +/- 104). Twice a day long acting sustained release isosorbide dinitrate is as effective as four times a day conventional short acting isosorbide dinitrate. Such a regimen is likely to lead to a better patient compliance and ease of antianginal therapy.

Résumé

One hundred and ninety five patients who underwent successful percutaneous transluminal coronary angioplasty (PTCA) for single vessel disease and have been followed up for more than 6 months are being reported. Angiography was done routinely in first 20 patients (Group 1) 8 to 15 weeks (mean 9.6 weeks) after PTCA. Restenosis (loss of 50% of the initial improvement in luminal diameter) was seen in 4 patients (20%). The remaining 175 patients (Group II) have been followed up clinically and subjected to serial exercise testing. Coronary angiography was performed only if symptoms and/or objective evidence of ischemia recurred. In this group, restenosis suspected clinically and confirmed by angiography occurred in 37 patients (21%), 2 to 23 weeks (mean 12.5 weeks) after PTCA. The restenosis rate for the entire patient population was 21%. In general the restenosed lesions were longer and tighter than the lesions before PTCA. A comparison of 41 patients with restenosis with those who did not have clinical restenosis revealed a proximal left anterior descending artery (LAD) involvement (66% vs 31%, p = 0.01), crescendo unstable angina (37% vs 16% p = 0.05), length of pre PTCA stenotic lesion greater than or equal to 1 cm (41% vs 27.5%, p less than 0.05), absence of intimal haziness in immediate post PTCA angiogram (27% vs 16%, p less than 0.05) and residual stenosis greater than or equal to 25%, (34% vs 14% p less than 0.05) in the restenosis group. Repeat PTCA was done in 30 patients with a 96% success rate; 4 patients required coronary artery bypass grafting (CABG). Restenosis after PTCA is a significant problem in our experience.(ABSTRACT TRUNCATED AT 250 WORDS)

Résumé

Estimation of antithrombin III, alpha 2 macroglobulin and alpha 1 antitrypsin in patients with stable and unstable angina and acute myocardial infarction (15 cases each) were carried out. Twenty age, sex and weight matched healthy subjects were included as controls. Mean platelet factor 4(PF4) levels measured in 10 cases of each subgroup were significantly elevated in myocardial infarction (MI) (48.4 +/- 15.16 ng/ml) and III unstable angina patients (44.7 +/- 15.9 ng/ml) as compared to controls (25.42 +/- 12.47 ng/ml; P less than 0.01). Mean antithrombin III (AT III) levels were markedly reduced in all patients with MI (39.65 +/- 12.8% of normal pooled plasma) and unstable angina (37.9 +/- 16.6% of normal pooled plasma) and in 9 patients with stable angina. Alpha I antitrypsin and alpha 2 macroglobulin levels in these cases showed no significant difference compared to normals. Reduced AT III in coronary artery disease suggests a prethrombotic tendency in these patients. Raised PF4 levels in acute phase of the disease suggests heightened platelet activation.

Résumé

We report the use of ketoconazole to control disseminated intravascular coagulation due to prostatic carcinoma. Clinical improvement in the condition of the patient was noted in 48 hours and coagulation profile became normal in 10 days.
