AimRight ventricular (RV) systolic function in patients with hypertensive heart disease (HHD) is not well characterised. The primary aim of this study was to assess the systolic function of the right ventricle in patients with HHD using tricuspid annular-plane systolic excursion (TAPSE).MethodsThe study was cross-sectional in design and carried out in Kano, Nigeria. Patients were recruited if they had HHD on echocardiography and were at least 15 years of age. Patients with other cardiac pathologies such as ischaemic and valvular heart diseases were excluded. Patients were considered to have abnormal RV systolic function if they had reduced values of TAPSE (< 15 mm). A p-value of < 0.05 was considered statistically significant.ResultsA total of 186 patients were serially recruited over seven months. Of these, 131 (70.4%) had normal RV systolic function (group 1) and 55 patients (29.6%) had abnormal function (group 2). Group 2 patients were older (p = 0.002) and had a higher prevalence of peripheral oedema (p = 0.002), moderate to severe dyspnoea, higher heart rate and lower left ventricular ejection fraction (p < 0.001). Atrial arrhythmias were also more prevalent among group 2 patients (p < 0.05). The best correlate to TAPSE was the septal mitral annularplane systolic excursion (r = +0.541, p < 0.001). Several variables such as age predicted the presence of reduced TAPSE.ConclusionThe study found that almost one-third of patients with HHD in Kano had RV systolic dysfunction as defined by reduced TAPSE, and these patients had a greater prevalence of factors associated with morbidity and mortality.

“…R ight ventricular (RV) systolic function is an important prognostic factor in heart failure (HF) with longitudinal systolic amplitude of motion and myocardial strain predicting exercise capacity and survival (1)(2)(3)(4). Such measurements of RV free wall have proved essential in contributing to 80% of its stroke volume and are able to explain the cavity adaptive mechanisms to volume and pressure overload (5).…”

“…RV indices of myocardial performance, tri cuspid annular systolic excursion and subjective visual estimations of RV function have been used to assess RV perfor mance [6][7][8]. However, none of these measures are well validated [9]. The best standard for assessing RV function appears to be MRI [10]; however, this remains a novel application, with large-scale validation studies still lacking.…”
