Supernormal functional reserve of apical segments in elite soccer players: an ultrasound speckle tracking handgrip stress study.

Abstract

Ultrasound speckle tracking from grey scale images allows the assessment of regional strain derived from 2D regardless of angle intonation, and it is highly reproducible. The study aimed to evaluate regional left ventricular functional reserve in elite soccer players. 50 subjects (25 elite athletes and 25 sedentary controls), aged 26 +/- 3.5, were submitted to an echo exam, at rest and after the Hand Grip (HG) test. Both standard echo parameters and strain were evaluated. Ejection fraction was similar in athletes and controls both at rest (athletes 58 +/- 2 vs controls 57 +/- 4 p ns) and after HG (athletes 60 +/- 2 vs controls 58 +/- 3 p ns). Basal (septal and anterior) segments showed similar strain values in athletes and controls both at rest (athletes S% -19.9 +/- 4.2; controls S% -18.8 +/- 4.9 p = ns) and after HG (athletes S% -20.99 +/- 2.8; controls S% -19.46 +/- 4.4 p = ns). Medium-apical segments showed similar strain values at rest (athletes S% -17.31 +/- 2.3; controls S% -20.00 +/- 5.3 p = ns), but higher values in athletes after HG (athletes S% -24.47 +/- 2.8; controls S% -20.47 +/- 5.4 p < 0.05) In athletes with physiological myocardial hypertrophy, a brief isometric effort produces enhancement of the strain in medi...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Athletic Heart Syndrome

Athletic heart syndrome refers to the physiological and morphological changes that occur in a human heart after repetitive strenuous physical exercise. Here is the latest research.
