    Area of Science:

    • Cardiovascular Physiology
    • Pharmacology

    Background:

    • Calcium ions (Ca++) are crucial for cardiovascular functions, including cardiac electrophysiology and myocardial contraction.
    • Calcium influx into cardiac and vascular smooth muscle cells is a key target for therapeutic intervention.

    Purpose of the Study:

    • To review the role of calcium ions in cardiovascular physiology.
    • To discuss the mechanisms and therapeutic applications of calcium channel blockers.

    Main Methods:

    • Literature review of studies on calcium channel blockers.
    • Analysis of the physiological impact of calcium ions on the cardiovascular system.

    Main Results:

    • Calcium channel blockers modulate calcium influx, affecting heart rate and contractility.
