Read your symptoms — a cardiologist’s framework.
Cardiovascular symptoms are among the most anxiety-provoking experiences a patient can have — and among the most frequently misunderstood. Most palpitations are benign. Most chest discomfort is not a heart attack. But some symptoms that seem minor are early warnings of serious disease.
All symptoms guides
This guide series gives you a cardiologist’s framework for interpreting cardiovascular symptoms — what they mean, what they don’t mean, and when to seek evaluation. Written and reviewed by Dr. Regina Druz, MD, MBA, FACC, FMCP-M.

A systematic approach to chest pain — cardiac vs. non-cardiac causes, red flags, and what to do immediately.
Shortness of Breath and Heart Disease
When breathlessness signals a cardiovascular problem — and what tests actually reveal the cause.
Dizziness and Heart Health
The cardiac causes of dizziness, lightheadedness, and near-syncope — and how they are evaluated.
Fatigue as a Heart Symptom
Why unexplained fatigue can be the earliest sign of cardiovascular dysfunction — and which biomarkers to check.
When to Go to the ER vs. See a Cardiologist
A practical decision framework for cardiovascular symptoms — what can wait for an appointment and what cannot.
