    Area of Science:

    • Cardiology
    • Pharmacology

    Background:

    • Effort angina is triggered by myocardial oxygen supply-demand imbalance.
    • Assessing the critical level of myocardial oxygen consumption is key in coronary artery disease (CAD).

    Purpose of the Study:

    • To evaluate the efficacy of various anti-anginal drugs and their combinations in patients with effort angina.
    • To determine the optimal therapeutic strategy for managing angina symptoms in CAD.

    Main Methods:

    • Exercise electrocardiogram (ECG) testing was used to assess patient responses.
    • Patients received placebo, nitrate derivatives, beta-blockers, and calcium inhibitors, individually and in combination.

    Main Results:

    • Nitrate derivatives and calcium inhibitors demonstrated greater efficacy than beta-blockers.
    • Combinations of beta-blockers with other agents enhanced anti-anginal effects.
    • Combined therapy mitigated undesirable hypotensive and antiarrhythmic side effects associated with beta-blockers.

    Conclusions:

    • Nitrate derivatives and calcium inhibitors are effective first-line treatments for effort angina.
    • Combining beta-blockers with other anti-anginal drugs offers a beneficial therapeutic approach.
    • Combination therapy optimizes angina management in CAD patients by enhancing efficacy and minimizing side effects.
