Circulating endothelin-1 levels in type 2 diabetic patients with ischaemic heart disease.

To investigate whether circulating endothelin-1 (Et-1) may be related to the increased incidence and severity of ischaemic heart disease in type 2 diabetes mellitus, we compared the concentrations in type 2 diabetic patients and in non-diabetic patients with coronary artery disease (CAD) angiographically documented. Plasma levels of Et-1 were determined in 34 type 2 diabetic patients with CAD (16 with stable angina, 6 with unstable angina, 12 with previous myocardial infarction) and in 19 nondiabetic patients with CAD (4 with stable angina, 5 with unstable angina, 10 with previous myocardial infarction). Fifteen diabetic patients without CAD and 9 healthy volunteers served as control subjec…

Treatment of patients with duodenal ulcer positive for helicobacter pylori infection: ranitidine or omeprazole associated with colloidal bismuth subcitrate plus amoxicillin

Abstract This study evaluated treatment of patients affected with duodenal ulcer positive for Helicobacter pylori . We compared patients treated with ranitidine plus amoxicillin plus colloidal bismuth subcitrate (n = 20) with patients treated with omeprazole plus amoxicillin plus colloidal bismuth subcitrate (n = 20) with regard to: (1) healing of duodenal ulcer; (2) eradication of H pylori ; and (3) recurrence of ulcer. Baseline and follow-up for 24 months were performed through clinical, laboratory, and endoscopic tests. The ulcer healing rate was 95% in the ranitidine group and 100% in the omeprazole group; the H pylori eradication rate was 90% and 95%, respectively. During follow-up, on…

The impact of coexistent diabetes on the prevalence of coronary heart disease.

Abstract The increased risk of developing cardiovascular disease in diabetic population has been well documented, but the prevalent mechanism of this susceptibility is still only partly explained. We compared the impact of diabetes on ischemic heart disease in patients hospitalized in a public general hospital over a 10-year period. The prevalence of coronary heart disease (CHD) was consistently higher among diabetic population [namely, among non-insulin-dependent diabetes mellitus (NIDDM) patients] when compared with the nondiabetic population. The prevalence was similar in both genders, increasing with age, and was independent from body-mass index, history of smoking, metabolic control, o…

Effects of dynamic exercise and metabolic control on left ventricular performance in insulin-dependent diabetes mellitus

In subclinical diabetic cardiomyopathy, previous reports did not positively correlate the altered cardiac performance with metabolic parameters. Fifteen insulin-dependent diabetic subjects, without any clinical or instrumental evidence of heart diseases, were studied. Signs of diabetic microangiopathy were absent. Systolic time intervals, metabolic and hormonal parameters (blood glucose, free fatty acids, blood lactate and plasma norepinephrine) were evaluated at rest and after dynamic exercise during poor (MAGE 6.36 +/- 0.72 mmol/l) and good (MAGE 3.46 +/- 0.66 mmol/l) metabolic control, obtained by means of insulin therapy. Rest values of systolic time intervals were normal during poor an…
