[Cardiohemodynamics and microcirculation in patients with ischemic heart disease undergoing beta-adrenergic receptor
Insights
Anaprilin may worsen angina in middle-aged patients with coronary atherosclerosis. Nonachlazin can reduce angina but requires high physical tolerance, impacting treatment strategies for ischemic heart disease.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Ischemic heart disease (IHD) involves coronary artery narrowing.
- Beta-adrenodependent vasodilation may be impaired in IHD patients.
Purpose of the Study:
- To evaluate the effects of anaprilin and nonachlazin on IHD patients.
- To assess drug impact on clinical course and hemodynamics.
Main Methods:
- Study included 76 IHD patients with 50-75% coronary stenosis.
- Coronography was used to assess stenosis.
- Clinical and hemodynamic effects of anaprilin and nonachlazin were analyzed.
Main Results:
- Anaprilin may increase angina attack frequency in middle-aged patients with initial coronary atherosclerosis.
- Nonachlazin reduces angina manifestations.
- Nonachlazin use is limited to patients with high physical load tolerance.
Conclusions:
- Anaprilin's use requires caution in specific IHD patient groups.
- Nonachlazin offers angina relief but has specific patient selection criteria.
- Individualized treatment is crucial for managing ischemic heart disease.
Abstract:
A study of 76 patients with ischemic heart disease is presented who revealed during coronography stenosis of one-three coronary arteries equalling 50-75% of the vessel lumen. Analysis of the effect of anaprilin and nonachlazin on the clinical course and hemodynamics revealed that in patients with initial coronary atherosclerosis of middle age beta-adrenodependent vasodilation of the coronary arteries decreased. In these patients anaprilin may increase the frequency of attacks of spontaneous stenocardia. On the contrary, nonachlazin reduces manifestations of stenocardia but it may be used only in patients with a high tolerance to physical load.
