Cardiologist Thomas E. Diggs, MD has practiced cardiovascular medicine since 1981 and serves Coronado Island through San Diego Heart & Vascular Associates at Suite 250, 230 Prospect Place, 92118. Dual board-certified in Internal Medicine (1985) and Cardiovascular Disease (1987) by the American Board of Internal Medicine, the George Washington University School of Medicine graduate completed his cardiology fellowship at Naval Medical Center San Diego — a military training pipeline that established lasting referral ties with the cardiovascular wellness and prevention programming at Peak Health Group on the island. The Coronado practice manages hypertension, heart failure, coronary artery disease, valvular disorders, and arrhythmia through on-site echocardiography, stress testing, Holter monitoring, and vascular Doppler imaging, with interventional catheterization performed at affiliated Sharp Coronado and Scripps Mercy hospitals. Cardiac medication management routes prescriptions through island dispensaries including Walgreens Pharmacy on Orange Avenue for anticoagulant titration and statin therapy continuity. Highest-complexity cases include transesophageal echocardiography-guided cardioversion for persistent atrial fibrillation and nuclear myocardial perfusion imaging with pharmacologic stress protocols for patients unable to exercise.
