ABSTRACT

Heart Failure with preserved Ejection Fraction (HFpEF), like other heart failure syndromes, is heterogeneous in etiology and pathophysiology, rather than a single disease. HFpEF may account for about half of all patients with heart failure. Patients have symptoms and signs of HF with normal or near normal left ventricular EF (LV EF>50 %). The classical risk factors for developing HFpEF include advanced age and co-morbidities, notably hypertension, atrial fibrillation, and the metabolic syndrome. When complicated by increasing congestion requiring hospital admission, the prognosis is poor; 30% or more of such patients will die within 1 year (nearly two-thirds die from cardiovascular causes). Patients with chronic stable symptoms have a better prognosis. Patients with HFpEF represent an important group of patients presenting in clinical practice with HF. Overall, it appears that patients with HFpEF are at lower risk of death than patients with HFrEF, although mortality remains high in both groups. Application of the same therapeutic hypotheses that have been successfully utilized among patients with HFrEF have not been demonstrated to result in improved survival

ABSTRACT

Nous rapportons dans cette étude les aspects épidémiologiques, diagnostiques, évolutifs et pronostiques de l'insuffisance cardiaque du sujet âgé de plus de 15 ans en milieu hospitalier nigérien. C'est une étude prospective menée en quatre (4) mois. Elle a concerné des sujets des deux sexes âgés de plus de 15 ans, admis dans un tableau d'insuffisance cardiaque. Nous avons inclus 103 cas soit 35,15% des 293 patients: 59 hommes (57,30%), 44 femmes (42,70%) (p =1,34) âgés en moyenne de 55,05 ans (extrêmes : 17 et 96 ans), la tranche d'âge la plus touchée était celle de plus de 65 ans (n= 36, soit 34,96%). Les facteurs de risque les plus fréquents étaient l'HTA (n=59, soit 49,50%), le tabac (n=13, soit 12,62%), le diabète (n=9, soit 8,73%).L'insuffisance cardiaque était globale (n = 79, soit 76,70%), gauche (n=21, soit 20,38%), et droite exclusive (n=3, soit 2,91%). Les cardiopathies en cause étaient, ischémiques (n=37, soit 35,92%), hypertensives (n = 32, soit 31,06%), les valvulopathies (n=12, soit 11,65%), CMPP (n=8, soit 7,76%), un cœur pulmonaire chronique a été objectivé dans 4 cas (3,88%) de même qu'une péricardite dans 4 cas (3,88%), les cardiomyopathies hypertrophiques (n=3, soit 2,77%). Une endocardite dans 1 cas et une cardiothyréose chez un seul patient. Le traitement a été exclusivement médical avec les diurétiques dans 94,17%, les inhibiteurs de l'enzyme de conversion (IEC) dans 94,20%, les bétabloquants (BB) dans 52,42% et les dérivés nitrés dans 18,44%. La létalité a été de 5,82% (n=6). La prévention consiste à lutter contre l'ensemble des facteurs de risque notamment l'HTA dont la prévention primaire s'avère ainsi nécessaire

ABSTRACT

Formulae for predicting functional capacity during 6-minue walk are lacking and the accuracy of the existing formulae has been challenged in deferent populations. The purpose of this study was to develop an equation that would be useful in predicting functional capacity in form of maximum oxygen consumption) (V0 ) in Chronic Heart Failure Patients (CHF) during exercise. Sixty-five subjects were recruited for the study. The procedure required the subjects to walk on a self paced speed on a 20 meter marked level ground for 6 minutes. The distance covered in 6 minutes was measured and the speed calculated. The result showed that the distance covered was highly correlated with the VO2 (0.65; p 0.01). The regression analysis revealed that a linear equation model developed was a good predictor ofV0 for the group. The study concluded that in situation where sophisticated equipments are lacking; this equation might be useful during exercise supervision for patients withCHF. [VO2 (ml kg-1 min-1)
