Long-term outcomes in heart failure with preserved ejection fraction: Predictors of cardiac and non-cardiac mortality.

ABSTRACT:

Aims

Heart failure (HF) with preserved ejection fraction (HFpEF) is associated with cardiovascular (CV) and non-CV events, but long-term risk is poorly studied. We assessed incidence and predictors of the long-term CV and non-CV events.

Methods and results

Patients presenting with acute HF, EF ≥ 45%, and N-terminal pro-brain natriuretic peptide > 300 ng/L were enrolled in the Karolinska-Rennes study in 2007-11 and were reassessed after 4-8 weeks in a stable state. Long-term follow-up was conducted in 2018. The Fine-Gray sub-distribution hazard regression was used to detect predictors of CV and non-CV deaths, investigated separately from baseline acute presentation (demographic data only) and from the 4-8 week outpatient visit (including echocardiographic data). Of 539 patients enrolled [median age 78 (interquartile range: 72-84) years; 52% female], 397 patients were available for the long-term follow-up. Over a median follow-up time from acute presentation of 5.4 (2.1-7.9) years, 269 (68%) patients died, 128 (47%) from CV and 120 (45%) from non-CV causes. Incidence rates per 1000 patient-years were 62 [95% confidence interval (CI) 52-74] for CV and 58 (95% CI 48-69) for non-CV death. Higher age and coronary artery disease (CAD) were independent predictors of CV death, and anaemia, stroke, kidney disease, and lower body mass index (BMI) and sodium concentrations of non-CV death. From the stable 4-8 week visit, anaemia, CAD, and tricuspid regurgitation (>3.1 m/s) were independent predictors of CV death, and higher age of non-CV death.

Conclusions

In patients with acute decompensated HFpEF, over 5 years of follow-up, nearly two-thirds of patients died, half from CV and the other half from non-CV causes. CAD and tricuspid regurgitation were associated with CV death. Stroke, kidney disease, lower BMI, and lower sodium were associated with non-CV death. Anaemia and higher age were associated with both outcomes.

Project description:Heart Failure with Preserved Ejection Fraction (HFpEF) is one of the most frequent causes of heart failure in the world's population (about 19-55%), and is commonly associated with a high rate of hospitalization (almost 70-80%) and with increased mortality (40-50% in a 5-year timeframe). The elderly are more often affected, with higher rates of hospitalizations than young people, and currently almost 70% of the population aged 65 years old has HFpEF. An increase in cardiomyocyte stiffness, thus resulting in diastolic dysfunction, increased filling pressures and heart failure with preserved ejection fraction are characteristics features of the disease. In addition, among the various causes of HFpEF, cardiac amyloidosis (CA) can provoke diastolic dysfunction and increased wall stiffness directly from intercellular deposition of insoluble proteic substances and their toxic activity. Totally, almost 30 different proteins are able to form deposits, but the most frequently involved are transthyretin and misfolded monoclonal immunoglobulin light chains, which bring to two clinical conditions called transthyretin amyloidosis (ATTR) and light-chain amyloidosis (AL). Although there has been increasing attention on ATTR-CA in recent years, the actual prevalence remains underestimated, especially in people of advanced age, as well as its real impact as a cause of HFpEF, and only data derived from autoptic exams are currently available. Moreover, CA itself often mimics HFpEF, and some conflicting data on the use of predictive scores are described in the literature. The close relationship between HFpEF and CA, especially in older population and the main pathophysiological mechanisms which bond these two conditions are described in this focused review. The need to screen red flags for ATTR-CA in elderly patients with HFpEF is urgently advised, because a prompt recognition of the disease can optimize the approach to the disease with an early therapeutic, life-saving choice.
