Impact of increased venous pressure on kidney function and mortality in cardiovascular patients with preserved ejection fraction.

Impact of increased venous pressure on kidney function and mortality in cardiovascular patients with preserved ejection fraction. Curr Med Res Opin. 2019 Dec 21;:1 Authors: Milkas A, Tsioufis K, Koliastasis L, Tsiamis E, Tousoulis D, Bartunek J, Vanderheyden M Abstract Background: Right but not left ventricular hemodynamic parameters have been found to be independently associated with adverse renal outcomes in patients with acute decompensated heart failure (HF).Aim: To investigate the hemodynamic profile of patients without acute decompensated heart failure and left ventricular ejection fraction>50% referred for elective left and right heart catheterization and to correlate left and right filling pressures, stroke volume and arterial blood pressure to renal function parameters. Subsequently, we tested the hypothesis that right ventricle and left ventricle hemodynamic parameters could predict all-cause mortality in our non-HF subjects.Methods: Between October 2009 and November 2010, 151 consecutive patients referred for elective left and right heart catheterization were studied and consequently followed up for a mean period of 8 years in order to identify all-cause mortality. Patient's initial cohort was subdivided in two groups according to right atrium pressure. The RAPRLOW group (Right Atrium Pressure ≤9 mmHg) and the RAPRHIGH group (Right Atrium Pressure>9mmHg)Results: No correlation between blood pressure, pulmonary capillary wedges p...

AbstractAimsThe PREPARE ‐MVR study (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve repair (MVR) and to explore the associations between/Repair patients) sought to investigate the alterations of right ventricular (RV) contraction pattern in patients undergoing mitral valve replacement/repair ( MVR) and to explore the associations between pre‐operative RV mechanics and early post‐operative RV dysfunction (RVD).Methods and resultsWe prospectively enrolled 42 patients (63  ± 11 years, 69% men) undergoing open‐heart MVR. Transthoracic three‐dimensional (3D) echocardio...

ConclusionsThe SV ‐INHIBITION study aims to answer the question whether PDE5 inhibitors should be prescribed in patients with an SV. This trial has been built focusing on the three levels of research defined by the World Health Organization: disability (exercise tolerance), deficit (SV function), and handicap (qual ity of life).

ConclusionsHVAD cannula coronal angle was associated with reduced right ventricular function and HRAE. Prospective studies evaluating surgical techniques to ensure optimal device positioning and its effects on HRAEs are warranted.

Authors: Toroghi HM, Lo KB, Ziccardi MR, Horn B, Kanjanahattakij N, Malik E, Penalver J, Rangaswami J, Gupta S, Amanullah A Abstract Worsening renal function in patients with heart failure with preserved ejection fraction is associated with poor outcomes. Pulmonary arterial capacitance is a novel right heart catheterization derived hemodynamic metric representing pulmonary arterial tree distensibility and right ventricle afterload. Given the strong association between heart failure, pulmonary hypertension, and kidney function, the goal of this study is to investigate the correlation between Pulmonary arterial capac...

CONCLUSIONS: NFLG-AS was the most prevalent form of LG severe AS and was associated with adequate left ventricular compensation and good prognosis. On the other hand, CLFLG-AS represents the heart-failure with reduced ejection fraction (HFrEF) form of AS and was associated with the worst prognosis, whereas PLFLG-AS represents the heart-failure with preserved ejection fraction (HFpEF) form of AS with intermediary prognosis. Both groups showed early hemodynamic reverse response after TAVR. PMID: 31566569 [PubMed - as supplied by publisher]

We present a case series of four patients with cardiog enic shock started on ivabradine who were unable to tolerate beta‐blockers.Methods and resultsFive patients identified with cardiogenic shock defined as a severe reduction in cardiac index (100] who were intolerant to beta ‐blockers. Each patient had a cardiac magnetic resonance imaging, echocardiogram, and coronary angiogram for determination of aetiology. Invasive haemodynamics via pulmonary artery catheterization were measured during initiation and titration of ivabradine (baseline, 6, 12, 24, and 48 h after iva bradine administration) with continuous telem...

AbstractA growing body of evidence has demonstrated that pulmonary arterial capacitance (PAC) is the strongest hemodynamic predictor of clinical outcomes across a wide spectrum of cardiovascular disease, including pulmonary hypertension and heart failure. We hypothesized that a ratio of right ventricular stroke volume (RVOT VTI) to the associated peak arterial systolic pressure (PASP) could function as a reliable non-invasive surrogate for PAC. We performed a prospective study of patients undergoing simultaneous transthoracic echocardiography and right heart catheterization (RHC) for various clinical indications. Measureme...

This study sought to discern which central (e.g., heart rate, stroke volume [SV], filling pressure) and peripheral factors (e.g., oxygen use by skeletal muscle, body mass index [BMI]) during exercise were most strongly associated with the presence of heart failure and preserved ejection fraction (HFpEF) as compared with healthy control subjects exercising at the same workload.BackgroundThe underlying mechanisms limiting exercise capacity in patients with HFpEF are not fully understood.MethodsIn patients with HFpEF (n = 108), the hemodynamic response at peak exercise was measured using right-sided heart catheterization...

CONCLUSIONS: The model results suggest improved intraoperative hypotension control in a hospital with annual volume 10,000 non-cardiac surgical patients is associated with mean cost reductions ranging from $1.2 to $4.6 million per year. Since the magnitude of the RCT mean estimate is similar to the unadjusted observational model, the institutional costs are likely at the upper end of this range.
