Heart attacks are often imagined as sudden, dramatic events, but cardiologists emphasize that the body usually gives warning signs well in advance. Dr. Ravi Prakash, Senior Consultant Cardiologist at PSRI Hospital, explains that many patients experience subtle symptoms 24 to 48 hours before a major cardiac event, a period known as the prodromal window.
During this phase, reduced blood flow stresses the heart long before a complete blockage occurs. Recognizing early symptoms can save lives. Key warning signs include extreme fatigue after minimal activity, intermittent chest discomfort that may feel like pressure or heaviness, and shortness of breath even at rest. Pain may radiate to the arm, shoulder, neck, jaw, or upper back, especially in women, older adults, and people with diabetes. Cold sweats, nausea, dizziness, and an unexplained sense of unease also indicate distress.
Dr. Prakash urges anyone experiencing a combination of these symptoms—especially those with risk factors like hypertension, diabetes, or a family history of heart disease—to seek medical attention immediately. Acting during the prodromal window can prevent severe heart damage and potentially save lives.
