Cardiologist highlights peak heart attack times and impact of noise on coronary arteries
Chronic road noise raises coronary artery disease risk, warns Dr. Khaled Al-Nemer, with a 10-decibel increase linked to an 8% higher risk.
Dr. Khaled Al-Nemer, a cardiologist and consultant at the College of Medicine, has warned of the heightened risk of coronary artery disease linked to chronic road noise. According to Al-Nemer, a 10-decibel increase in noise levels raises the risk by approximately 8%. In an X (formerly Twitter) post, he explained that continuous noise keeps the nervous system in a constant state of alertness, triggering the persistent release of cortisol and adrenaline hormones. This prolonged hormonal surge, he said, gradually damages the lining of blood vessels.
Al-Nemer highlighted the typical timing of heart attacks, noting that most occur between 6:00 a.m. and 11:00 a.m, with peaks around 8:30 and 9:00 a.m. He also pointed out that the most severe cases typically happen between 1:00 and 3:00 a.m. However, he noted that other factors may also influence these findings.
