Prognostic value of daytime heart rate, blood pressure, their products and quotients in chronic heart failure

“…According to BARDICHE-index authors lower SBP was associated with higher HF exacerbation rate independently of LVEF [29]. Several authors have demonstrated that higher SBP was independently related to improved cardiovascular survival in patients with CHF [13,21,24,30]. Surprisingly, this study did not confirm the relationship between SBP and MACE in the whole group of patients or in study subgroups.…”

“…Some authors have suggested that low daytime BP variability may also influence prognosis in patients with HF [23]. Sherazi et al [24] and revealed that the absence of hypertension, as well as elevated urea and lower LVEF ≤ 45% indicate increased risk of short and long-term mortality. The relationship between DBP and MACE has been discussed in other publications concerning this subject [8,25,26].…”

Incidence of chronic heart failure with preserved left ventricular ejection fraction in patients with hypertension and isolated mild diastolic dysfunction

“…The role of chronic heart ischemia as the cause of HFPEF was confirmed in other clinical studies even without concomitant impaired contractility. 8 In our study, CAD was an independent predictor of HFPEF.…”

“…Continuous variables were first evaluated for normal coronary artery disease (CAD), hypertrophic cardiomyopathy, congenital heart defects associated with ventricular hypertrophy, and diabetes. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] According to the European Society of Cardiology (ESC), the diagnosis of HFPEF requires 4 criteria to be met: the presence of signs and symptoms typical of HF, normal or only mildly reduced LVEF, no LV dilation, and relevant structural heart disease or left ventricular diastolic dysfunction (or both).…”

Clinical features of idiopathic restrictive cardiomyopathy

“…In normal or small LV, owing to increased passive stiffness of the LV, significant changes in pressure may be seen even with little or no detectable change in ventricular volume. [12] As Sherazi et al [13] reported, a smaller cavity in heart failure with preserved LV EF increased passive chamber stiffness. The small LV cannot accept venous return adequately, and such high LV filling pressure may worsen the symptoms of heart failure and lead to poor prognosis.…”
