Persistent High Heart Rate Raises Mortality Rate in CHD Patients
A high heart rate in patients with stable coronary heart disease raises the risk of complications even when other factors are under control.
The results of a large study presented at the October 2010 Canadian Cardiovascular Congress show that patients with stable coronary heart disease, but with a high heart rate, have a significantly higher risk of death than those with a lower heart rate. Researchers found that patients with heart rates greater than 78 had a 39 percent increased risk of suffering a major vascular event, a 77 percent increased risk of cardiovascular disease death, and a 65 percent increased risk of death from all causes. "Heart rate is the number of times your heart beats every minute," says Michael D. Faulx, MD, FACC, a staff cardiologist at the Heart and Vascular Institute and associate program director of the Internal Medicine Residency Program at Cleveland Clinic.
