LAGOS, Nigeria(VOICE OF NAIJA)- A cardiologist at Medipol University Esenler Hospital in Istanbul, Prof. Dr. Muhammet Hulusi Satilmisoglu, has warned that extreme heat can trigger life-threatening heart complications by placing extra strain on the cardiovascular system.
Prof Satilmisoglu explained that when temperatures rise, the body pumps more blood to the skin’s surface to release heat.
This process increases heart rate while excessive sweating causes fluid loss, making the blood more likely to clot.
The cardiologist noted that cardiovascular disease accounts for a large proportion of heat-related deaths, making people with existing heart conditions particularly vulnerable during periods of intense heat.
According to him, individuals who have suffered a heart attack, undergone bypass surgery, received a stent or been diagnosed with high blood pressure face a greater risk of serious complications when temperatures soar.
Satilmisoglu advised people in these high-risk groups to avoid unnecessary outdoor activities during the hottest part of the day and remain well hydrated.

He also urged immediate medical attention if symptoms such as severe fatigue, chest tightness, excessive sweating or confusion develop, warning that they could signal a serious cardiovascular problem.
Furthermore, the specialist said extreme heat triggers major physiological changes that can worsen underlying heart and blood vessel diseases, increasing the likelihood of medical emergencies.
To lower the risk, Satilmisoglu recommended drinking adequate amounts of water, maintaining electrolyte balance by eating fresh fruits and vegetables, avoiding strenuous physical activity and limiting outdoor exposure between 9 a.m. and 4 p.m.
He added that people living with heart failure should follow their doctor’s advice on fluid intake and medication adjustments during heatwaves rather than making changes on their own.
He also recommended wearing wide-brimmed hats and other sun-protective gear to help reduce the impact of extreme temperatures.
Notably, with heatwaves becoming more frequent in many parts of the world, health experts continue to encourage the public, especially those with pre-existing heart conditions to take preventive measures that can reduce the risk of heat-related cardiovascular complications.
