Impaired renal perfusion from left ventricular dysfunction is thought to be a principal underlying mechanism. Less is known about the influence of venous congestion, including the potential contribution of tricuspid regurgitation (TR). \u0000 \u0000 \u0000 \u0000Methods and Results.   Echocardiograms and a simultaneous (±1 day) blood sample from 196 HF patients were analyzed. Patients with at least moderate TR (n=78) had larger right-sided cardiac cavities, higher right ventricular systolic pressure, lower estimated glomerular filtration rate (eGFR), higher serum urea nitrogen (SUN) level, and SUN/creatinine ratio than patients with less than moderate TR (n=118). In multivariate linear regression analysis, TR severity (P=.003), older age (P<.001), and loop diuretic use (P=.008) were independently associated with lower eGFR, and use of inhibitors of the renin-angiotensin-aldosterone system was associated with higher eGFR (P=.001). TR severity (P<.001) and older age (P<.001) were independently associated with higher SUN value. TR severity (P=.004) and smaller left ventricular end-diastolic diameter (P=.048) were independent predictors of a higher SUN/creatinine ratio (P=.004). \u0000 \u0000 \u0000 \u0000Conclusions.  Although a causal relationship cannot be proven, we suggest that significant TR contributes to renal dysfunction in HF patients, probably by elevation of central and renal venous pressure.—Maeder MT, Holst DP, Kaye DM.

Limited data exist concerning the long-term incidence or prognosis of HF after MI, particularly in the era of coronary revascularization. \u0000 \u0000 \u0000 \u0000 Methods.  A population-based cohort of 7733 patients 65 years and older hospitalized for a first MI (International Classification of Diseases, 9th Revision Clinical Modification code 410.x) and without a prior history of HF was established between 1994 and 2000 in Alberta, Canada, and followed up for 5 years. \u0000 \u0000 \u0000 \u0000 Results.  During the index MI hospitalization, 2831 (37%) MI patients were diagnosed with new HF and 1024 (13%) died. Among hospital survivors who did not have HF during their index hospitalization (n=4291), an additional 3040 patients (71%) developed HF by 5 years, 64% of which occurred in the first year. In total, 5871 (76%) elderly patients who survived their first MI developed HF over 5 years. Among those who survived the index hospitalization, the 5-year mortality rate was 39.1% for those with HF during the index MI hospitalization compared with 26.7% among those without HF (P<.0001) during the index MI hospitalization. Over the study period, the 5-year mortality rate after MI decreased by 28%, whereas the 5-year rate of HF increased by 25%. \u0000 \u0000 \u0000 \u0000 Conclusions.  In this large cohort of elderly patients without a history of HF, HF developed in three-quarters in the 5 years after their first MI; this proportion increased over time as peri-MI mortality rates declined. New-onset HF significantly increases the mortality risk among these patients.—Ezekowitz JA, Kaul P, Bakal JA, et al.

In addition, during long-term follow-up (32±16 months), less events (combined for heart failure hospitalizations and death) were reported in patients with a concordant LV lead position.
