Sport and sudden death

Sudden death was defined as death that occurred 1 (one) hour after symptoms started. While this type of accident occurs with some frequency in everyday life, it is not even in athletes, when it occurs in athletes, there is usually a great commotion in the community due to the established assumption that anyone who makes sport minimized the risks in terms of their health. This potential impact is when it comes to famous athletes, especially in football where there have been several cases in recent times and that people easily forget.
Statistics say that the sudden death in athletes, previously healthy, is in the order of 0.0005% per annum. While the causes can be diverse, the etiology is the most frequently noted of cardiovascular origin. So we can mention a heart muscle disease of congenital origin (hypertrophic cardiomyopathy) as the star that leads all causes followed by the Marfan syndrome, anomalies of origin of the coronary arteries and stenosis of the aortic valve, all of congenital. Then, we can examine other causes such as heat exhaustion, bad asthma (asthma induced by effort), etc., usually very rare because the athletes are already well Sensitizing regarding the precautions to take to avoid these evils.
Regarding the hypertrophic cardiomyopathy and asymmetric septal hypertrophy or hypertrophic subaortic stenosis are dynamic entities that affect the myocardium (heart muscle) and that occur with shortness of breath (dyspnea), chest pain (angina) for arrhythmias and syncope almost always can be detected in an ergometric stress test (!). The cause of death in these individuals is associated with an excess of oxygen demand by myocardium unsatisfied which leads the above-mentioned symptoms and triggers arrhythmias that compromise life.
Something similar occurs with aortic stenosis, which implies a restriction on removal of blood from the heart by a congenital obstruction of the aortic valve.
Marfan syndrome is a complex disease with multiple pathologies in different devices, eg lens dislocation, thoracic aortic aneurysm, hiperextensibilidad with musculoskeletal disorders, pectum excavatum, arachnodactyly (long fingers), etc., all related to the underlying disease that is the laxity of the connective tissue. The increased mortality that this disease occurs is due to their cardiovascular events (rupture of an aortic aneurysm). The body's habit marfanoide biotype is longilíneo (tall and thin), a model of excellence in many sports.
With regard to congenital anomalies of the coronary arteries is very difficult to diagnose because the same carriers are usually asymptomatic and their physical examinations found no abnormalities.
What is important to emphasize is that most of these problems can and should be detected and treated properly. First clinical tests can detect single puffs characteristic of aortic stenosis or of hypertrophic cardiomyopathies. Also facing a habit marfanoide is quickly apply some studies to clarify the diagnosis. An electrocardiogram revealed the presence of arrhythmias as a guide to diagnosis and from the invaluable and Ergometry detecting abnormalities in the effort not to sleep. This is the goal on which to work to some deaths of athletes compete without the real knowledge of their cardiovascular response to exercise can be avoided.
Finally it is important to emphasize the need for thorough medical examinations, and pursuant to verify some of these sufferings, knowing that competitive sport should be avoided allowing a controlled and supervised physical activity with monitoring of cardiovascular function.
