Board-certified in both internal medicine and cardiovascular disease, David Hansen, MD maintains a Coronado office on 10th Street serving adult patients on Coronado Island. His 1970 UCLA David Geffen School of Medicine degree and University of Colorado Health residency established a clinical foundation distinct from the system-affiliated primary care at Scripps Clinic Coronado and the Sharp-network practices on Prospect Place. The practice's chronic disease management focus addresses diabetes, hypertension, hyperlipidemia, and cardiovascular risk stratification for the 92118 patient population, with bilingual English-Spanish consultations broadening access on the island. Cardiac rehabilitation counseling includes exercise prescription and activity-level clearances, with patients progressing to supervised fitness at Coronado Fitness Club once cardiovascular stress testing confirms safe exertion thresholds. The highest-complexity workups encompass stress-test interpretation, echocardiogram referral coordination, Holter monitor analysis for arrhythmia detection, and atrial fibrillation management protocols requiring anticoagulation titration.
