This effect may be involved in any beneficial role of heart rate lowering agents in preventing coronary heart disease. Higher heart rates may be an indication of poor heart function and higher than usual stress being placed on the hearts ability to circulate blood. Maximal stroke volume and cardiac output increase, contributing to a lower resting heart rate and longer diastolic filling time. While a fast heart rate isnt a sign of heart attack or heart disease, it can be a signal that your. Slowing the heart rate could potentially decrease the progression of atherosclerosis by reducing the local pro-atherosclerotic vascular environment. Even people with good overall health are at risk. Heart rate should be considered in every patient with coronary heart disease, especially since it is an easily measurable and reproducible parameter. Lower can be better, as long as it remains above 60. All these processes induce structural and functional changes of the endothelial cells, which are accumulated over the time in atherosclerosis-prone regions promoting atherosclerosis. Ask your health care professional what your resting heart rate should be. Although it may be difficult to define an optimal HR for a given individual, it seems desirable to maintain resting HR substantially below the traditionally defined tachycardia threshold of 90 or 100 beats/min. Additionally, once a person goes through menopause, they have an increased risk of coronary. Studies have found a continuous increase in risk with HR above 60 beats/min. Moreover, increased heart rate intensifies the pulsatile motion of the heart and, therefore, the frequency of the periodically changing geometry of the coronary arteries, thereby affecting the local hemodynamic environment. A person’s average heart rate at 10 weeks was 79.3 bpm, which increased to 86.9 bpm by 40 weeks. An elevated heart rate enhances the magnitude and frequency of the tensile stress imposed on the arterial wall and prolongs the exposure of coronary endothelium to the systolic low and oscillatory shear stress. If you have an arrhythmia that causes the heart to beat faster than normal, this is known as tachycardia. In this review we explore the pathophysiologic mechanisms involved in the pro-atherosclerotic effect of elevated heart rate, apart from its association with sympathetic tone. To calculate your perfect heart rate, you need to go one step further after subtracting your age from 220 bpm. Keep in mind that range gradually lowers as you age. Several epidemiological studies have reported that an elevated heart rate is associated with coronary atherosclerosis independently of other risk factors. However, you should be reaching your target heart rate of around 60 to 80 percent.
