CARDIOVASCULAR DISEASE AND DRUGS
Basic cardiovascular physiology and pathology depends on the control of heart rate, cardiac output, blood pressure, blood flow, ionic composition, RAAS, vascular endothelium, regulation of tissue perfusion, hypertension, dislipidaemias, atherosclerosis, blood clotting, ischaemic heart disease, cardiomyopathies, cardiac arrhythmias and cardiac failure.

Cardiovascular drugs: inotropic agents, b blockers, calcium antagonists, organic nitrates, anti-arrhythmics, ACE inhibitors, ATII (=AT1) antagonists, diuretics, cholesterol lowering drugs, clot-busters, anti-coagulants, anti-platelet drugs.

DRUGS TO TREAT ANGINA PECTORIS
Angina pectoris refers to a strangling or pressure like pain caused by cardiac ischaemia.
It’s a pain syndrome due to induction of an adverse oxygen supply / demand situation in portion of myocardium.
Drugs used exploit two main strategies: reduction of oxygen demand and increase of the oxygen delivery to myocardium.
Three types of anginal attack: stable angina, unstable angina and variant angina.

DRUGS TO TREAT HEART FALIURE
Clinical syndrome that
can result from any
structural or functional
cardiac disorder that
impairs the abilty of the
ventricle to fill with or
eject blood.

Therapeutic Uses of Digitalis Compounds
Heart Failure ↑ inotropy ↑ ejection fraction ↓ preload ↓ pulmonary congestion/edema Arrhythmias ↓ AV nodal conduction
(parasympathomimetic effect) ↓ ventricular rate in atrial flutter
and fibrillation Digitalis compounds have historically been used in the
treatment of chronic heart failure owing to their cardiotonic effect.
Ex: Digoxin, digitoxinMaghan Das

To treat CHF:
Ionotropic drugs: Digoxin, Dobutamine
Diuretics: Furosemide, Thiazide
Vasodilators: ACE inhibitors,AT1 antagonist, Nitrate
Beta blockers: Metroprolol
