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…
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…
Comparison of roxatidine and ranitidine in the treatment of refractory duodenal ulcer
Abstract Fourteen patients with duodenal ulcer not healed after treatment with ranitidine at the standard dosage of 300 mg/day for 12 weeks were enrolled in the study. Eight patients were treated with roxatidine acetate, 150 mg/day, for 8 weeks (group A); six patients received treatment with ranitidine, 600 mg/day, for 8 weeks (group B). Efficacy of treatment was evaluated on the basis of reduction of ulcer pain, lowering of maximal acid output (MAO) levels, and cicatrization of ulcer lesion. The patients treated with roxatidine showed a significant reduction in MAO levels after 4 weeks, whereas the patients treated with ranitidine showed a significant reduction in MAO levels after 8 weeks.…
