Newer studies also point to small increases in the width of the main blood vessel from the heart. These changes are felt to be ‘adaptive’ – that is, they reflect positive changes that allow the heart an increased ability to supply blood and oxygen to exercising tissues. Since the maximum heart rate tends to vary by individual and by age, the principle mechanism for the heart to increase its output is to increase the amount ejected per beat (also known as the stroke volume). This is achieved by increasing chamber size and compliance.
We try to help determine whose heart is normal and whose is not. We carry out maximal exercise tests with expired gas analysis and echocardiography (ultrasound) of the heart. Magnetic resonance imaging is valuable and provides higher resolution images that include the origins of the blood vessels of the heart. We sometimes make use of 24 hour blood pressure monitors to rule out occult high blood pressure. In rare cases, genetic testing can help.
Wadi El Neel Athletic heart center multidisciplinary approach to athlete management includes comprehensive assessment and screening the athlete to help maximize their body use of energy, reduce risk of energy and determine the exercise intensity that’s right for each athlete.
In addition to seeing athletes in clinic, we are cardiologists to many sport clubs & many sport federation . Fortunately, heart disease is very rare in athletes but there is interest and debate surrounding the best method of screening athletes for heart issues.
