How to identify subtle signs of heart strain

Heart attacks are critical medical emergencies that frequently occur without the dramatic warning signs typically expected, such as sudden collapse or crushing chest pain.

Dr Sandeep Thakkar, a senior consultant in interventional cardiology at Manipal Hospital, Patiala, explains that "silent" heart attacks develop quietly and can cause the same degree of permanent heart damage as classic attacks.

A silent heart attack occurs when blood flow to a segment of the heart is reduced or blocked, leading to tissue damage.

Dr Thakkar observes that these events are notably more common among women, older adults, and individuals with diabetes.

In many cases, the body begins sending quiet signals nearly a week in advance, gradually building up without the obvious alarms that would prompt an immediate hospital visit.

Five Critical Warning Signs

Dr Thakkar has outlined five essential symptoms that should never be ignored, especially if they persist or worsen over several days:

• Persistent Fatigue: Unusual tiredness that does not improve with rest occurs as the heart struggles to pump oxygen-rich blood.
• Shortness of Breath: Feeling winded after mild exertion or needing breaks while walking suggests poor heart function and fluid backup in the lungs.
• Unexplained Dizziness: Sudden light-headedness or nausea can result from the nervous system reacting to changes in blood flow, often mistaken for dehydration.
• Sleep and Anxiety Shifts: Waking up suddenly at night or feeling a new sense of restlessness can be the body’s way of signalling heart strain.
• Intermittent Chest Discomfort: Brief, irregular discomfort is frequently misinterpreted as indigestion, acidity, or gastric pain.

The cardiologist advises that noticing these signs early can prevent the need for major surgical interventions, such as angioplasty or coronary artery bypass grafts.

Seeking a medical evaluation when symptoms are still mild allows for appropriate medication that can protect long-term heart health.

Early intervention is not just about survival; it is about preventing the serious, lasting complications associated with undiagnosed cardiac events.
