RIGHT VENTRICLE IN PATIENTS WITH ARTERIAL HYPERTENSION AND B STAGE HEART FAILURE

Abstract

Objective: According to ACC/AHA Heart failure (HF) classification the A stage of HF is a high risk for HF but without structural heart disease or symptoms; B stage is a structural heart disease but without signs or symptoms of HF. One of the most important risk factors of HF is Arterial Hypertension (AH). There is no information about Right Ventricular (RV) structure and function, in patients with stage A and B of HF. The aim of our research was to study RV structure and function in patients with AH and stage A or B HF. Design and method: We studied 163 patients with AH (female-76, male 87). 45 in stage A and 118 in stage B HF. All patients undergone standard EchoCG examination. RV outflow tract (RVout) was examined by M-mode from parasternal short axis and PW TDI from subcostal position (RVoutTDI). The shape of RWoutTDI was different from the Tricuspid anulus TDI. It consists from positive isometric contraction (ICTs), isotonic contraction (s), negative early diastolic (e) late (a) diastolic waves velocities, two negative (e1) positive (e2) isometric relaxation waves. We measured the pick velocities of these waves in cm/sec and isometric contraction (ICT), ejection (RVET) and isometric relaxation time (IRT) intervals in msec. On M-mode EcoCG of RVoutRV we measured Diastolic Diameter (Dd) systolic diameter (Ds), fractional shortening (RWoutFS) and RW wall systolic excursion (RWexc). Results: We did not find any significant differences between in RV EcoCG, RVout, RVoutTRI and Tricuspid annulus TDI parameters between the A and B Heart Failure groups in patients wit Arterial Hypertension. Conclusions: There is no difference in EchoCG parameters between A and B Heart Failure groups in patients with Arterial Hypertension.
