Dementia screening in elderly high-risk patients following heart failure decompensation may predict unfavorable long-term clinical outcomes

Clinical characteristics and long-term outcomes of patients with heart failure with improved ejection fraction. First Polish experience from LECRA-HF registry

PURPOSE

Heart failure (HF) with improved ejection fraction (HFimpEF) is a new category of HF introduced in the newest European Society of Cardiology guidelines. However, clinical characteristics and long-term outcomes of HFimpEF patients remain insufficiently elucidated. We sought to characterize Polish HFimpEF patients and determine their long-term mortality.

MATERIAL AND METHODS

Of 1186 patients enrolled in the single-center Lesser Poland Cracovian Heart Failure (LECRA-HF) registry between 2009 and 2019 and hospitalized due to HF decompensation, 340 (28.7%) were those with HF with reduced ejection fraction (HFrEF). Based on follow-up echocardiography, 61 (17.9%) of them were classified as HFimpEF and the remaining as HFnon-impEF.

RESULTS

HFimpEF patients were more frequently females (P ​< ​0.001), had higher baseline left ventricular ejection fraction (LVEF, P ​< ​0.001), had less often a history of diabetes (P ​= ​0.024), severe chronic kidney disease (P ​= ​0.026) or prior myocardial infarction (P ​= ​0.008) than HFnon-impEF patients. By multivariable analysis the HFimpEF diagnosis was independently predicted by baseline NYHA I/II (odds ratio [OR] 2.347, 95% confidence interval [95%CI] 1.020-5.405), non-ischemic etiology (OR 3.096, 95%CI 1.587-6.024), lack of diabetes mellitus (OR 2.016, 95%CI 1.059-3.846) and higher baseline LVEF (OR 1.084, 95%CI 1.042-1.126, per 1%). Within the median 49 (25-77) months all-cause mortality was lower in HFimpEF than in HFnon-impEF (10.8 vs 16.4%/year, P ​= ​0.004).

CONCLUSIONS

Our findings indicate that every sixth Polish patient with HFrEF has a chance to improve LVEF during follow-up and to become a HFimpEF patient. Baseline characteristics of HFimpEF patients are different from HFnon-impEF. Simultaneously, the HFimpEF diagnosis is associated with higher long-term survival.

Cardiovascular medicine: a year in review

Cardiovascular medicine is facing several challenges in the current era, dominated by the rapid spread of a previously unknown virus around the world. Indeed, the 2020 COVID-19 pandemic set the course of cardiovascular science and education in an extraordinary way, hogging the attention of the medical community. Notably, while COVID-19 impacted research progress, there has been considerable effort in exploring topics of great interest, from the management of acute coronary syndromes to new horizons in the treatment of heart failure, from novelties in the surgical treatment of cardiovascular disease to new data on implantable cardiac devices, and from new diagnostic applications of multimodal imaging techniques to relevant basic science findings. Minerva Cardiology and Angiology, formerly Minerva Cardioangiologica, has strived to inform its readers on these topics and novelties, aiming for a succinct yet poignant melding of timeliness and accuracy. Accordingly, the purpose of this narrative review is to highlight and summarize the major research and review articles published during 2020. In particular, we provide a broad overview of the novelties identifying six major areas of interest in the field of cardiovascular sciences in which new evidences have contributed to improving prevention, diagnosis and treatment of heart and vessels diseases.
