Cardiology
Discipline dealing with heart and vascular disease — diagnostic and interventional, plus cardiac surgery.
Cardiology covers everything from hypertension management to advanced interventions (angioplasty, TAVR, electrophysiology). Cardiac surgery is a separate specialty — open procedures like CABG and valve replacement. The two specialties work closely on complex cases.
