Heart Murmur Signs That Could Mean Something Serious
Shortness Of Breath
Certain types of murmurs, such as those associated with the thickening or narrowing of the aortic valve in older individuals, are the result of the heart having to work harder to pump blood throughout the body. Aortic sclerosis, which is the thickening or stiffening of the aortic valve, or aortic stenosis, which is the narrowing of the aortic valve, can cause murmurs as well as shortness of breath. Trouble breathing may indicate the need for a valve replacement. Also, physical activity or exercise are common causes for rapid blood flow through the heart, which is an indicator of an innocent heart murmur as well as shortness of breath.
