Sobrepesos e a estatística.


.
Conclusion: In subjects at low-to-moderate cardiovascular risk, overweight is a key determinant of the reduction of global LV longitudinal function as assessed by 2D strain.

Já descrevemos aqui artigos e confusões com o uso do Doppler Tecidual para classificar obesos com “doentes ao Doppler”.
Erros de angulação podem muito bem prejudicar essa análise.
.
Peak ventricular longitudinal strain (PVLS) no EchopacK também pode ser confuso???
.
De qualquer forma, a diferença estatística é significante, mas não é relevante.

Onda S´para avaliar reserva. Simples e fácil.

Across all subjects the strongest relationship with peak oxygen uptake (pVO2) was with peak left ventricular systolic tissue velocity (S′) during exercise (r = 0.84, P < 0.001
.

.
Conclusion
There is a very strong relationship between measurements of S′ during exercise and exercise capacity. The previously observed poor correlation with standard measures of systolic and diastolic cardiac function may be explained both by the load dependence of parameters such as ejection fraction and by reliance on resting as opposed to exercise assessment.

Muito simples e rápido. É só pedalar e fazer o Doppler tecidual.

E serve para várias patologias
