Every Minute Counts: Cardiologists Warn of Silent Killer

COLOMBO (News 1st); Health authorities in Sri Lanka are raising alarms over the growing threat of heart attacks, which continue to be the leading cause of death both globally and locally. 

According to medical experts, between 30% to 40% of individuals who suffer a heart attack die at the moment of onset, underscoring the urgency of early detection and immediate medical intervention.

Dr. Sampath Withanawasam, Chairman of the Sri Lanka College of Cardiology, emphasized the critical nature of timely treatment.

“In cases of severe heart attacks, where coronary arteries are completely or nearly completely blocked, heart muscle begins to die within 20 to 30 minutes. This process can continue for up to 12 hours, and in some patients, even less,” he explained. “If a patient arrives at the hospital 24 or 48 hours after the onset, the damaged heart tissue cannot be revived.”

He urged the public to seek medical attention immediately upon experiencing any symptoms related to heart disease, as delays can be fatal.

Risk Factors and Prevention:

Dr. Disna Amaratunga, a consultant cardiologist, highlighted several risk factors contributing to heart disease. 

“Family history plays a significant role. Men are generally at higher risk than women, and age is another unavoidable factor,” she said. “However, there are modifiable risks we can control—such as managing chronic conditions, quitting smoking, regular exercise, and reducing stress.”

She recommended at least 20 minutes of continuous physical activity five days a week, including walking, swimming, or cycling. While weightlifting may not be suitable for some heart patients, other sports like cricket and badminton are encouraged.

Dr. Amaratunga also warned against altering prescribed heart medications without consulting a specialist. “Procedures like stenting or bypass surgery are not the end of treatment. Medications must be taken exactly as prescribed. If you need dental work or surgery, inform your doctors about your heart condition so your medication can be adjusted appropriately.”
