Relationship between hypertension and angina pectoris.

P J Richardson, L S Hill

    British Journal of Clinical Pharmacology
    |January 1, 1979
    PubMed
    Summary

    Beta-blockers are recommended for treating angina pectoris in patients with hypertensive heart disease. These drugs effectively reduce blood pressure, heart rate, and myocardial contractility, thereby lowering the heart

    Area of Science:

    • Cardiology
    • Pharmacology
    • Hypertension Research

    Background:

    • The relationship between angina pectoris and hypertensive heart disease involves multiple physiological factors.
    • Vascular resistance impacts myocardial oxygen supply, while oxygen demand is influenced by blood pressure, cardiac filling times, and sympathetic activity.

    Purpose of the Study:

    • To identify optimal treatment strategies for angina pectoris in patients diagnosed with hypertensive heart disease.
    • To evaluate the efficacy of specific pharmacological agents in managing myocardial ischemia within this patient population.

    Main Methods:

    • Review of physiological factors influencing myocardial oxygen supply and demand in hypertensive heart disease.
    • Analysis of treatment approaches targeting myocardial ischemia.
    • Evaluation of beta-adrenoceptor antagonists based on their effects on blood pressure, heart rate, and contractility.

    Main Results:

    • Beta-adrenoceptor antagonists effectively reduce blood pressure, heart rate, and myocardial contractility.
    • These reductions lead to decreased myocardial oxygen demand, crucial for managing ischemia.

    Conclusions:

    • Beta-adrenoceptor antagonists are suggested as the most suitable treatment for angina pectoris in hypertensive heart disease.
    • Their mechanism of action directly addresses the factors contributing to myocardial ischemia in these patients.
