Why the study?
Is tricuspid regurgitation within the normal range associated with the development of left ventricular diastolic dysfunction in patients with uncomplicated hypertension?
Is tricuspid regurgitation within the normal range associated with the development of left ventricular diastolic dysfunction in patients with uncomplicated hypertension?
Tricuspid regurgitation within the normal range (velocity < 2.8 m/s) may be related to the development of left ventricular diastolic dysfunction in patients with uncomplicated hypertension.
Should not change TR assessment in hypertension; leaves open whether PASP or LA fractions improve diastolic dysfunction prediction.
AIM: Tricuspid regurgitation (TR) with the maximum velocity >2.8m/s has been newly integrated into the diagnostic criteria for left ventricular (LV) diastolic dysfunction. Although the maximum velocity of TR within the normal range (TR < 2.8m/s) is frequently detected in hypertensive patients and is associated with enlarged left atrial (LA) volumes, the influence of TR < 2.8m/s on LV diastolic dysfunction remains unknown in uncomplicated hypertension. METHODS: + 5 mmHg. RESULTS: The maximum velocity of TR or PASP saw a positive correlation, and LA total or passive emptying fractions saw an inverse correlation with LV diastolic dysfunction in hypertensive patients with TR < 2.8. In contrast, pulse pressure and LV mass saw positive correlation in hypertensive patients without TR. A stepwise ordinal logistic regression analysis indicated that PASP and LA passive emptying fractions were associated with LV diastolic dysfunction in hypertensive patient with TR < 2.8m/s. CONCLUSION: The presence of TR may be related to the development of LV diastolic dysfunction in hypertensive patients with TR <2.8m/s.
