Introduction
heart failure with preserved ejection fraction (HFpEF) is a growing public health problem. Its prevalence among heart failure patients increases over time, accounting for at least 50 % of all hospital admissions for HF. Nevertheless, no single guideline exists for diagnosis or treatment for HFpEF, and older age or comorbidities are additional factors that confuse etiology and complicate prognosis. Moreover, there are few data regarding the consequences of HFpEF on other recurrent pathologies.
Aims
to assess the prognostic impact of a pre-existing HFpEF on patients ospidalized for intercurrent episodes of atrial fibrillation (AF) or acute pulmonary embolism (PE)
Methods
We performed a retrospective evaluation of 194 patients, consecutively hospitalized in our unit of Cardiology with a diagnosis of paroxysmal AF or acute PE, from April 2017 to October 2020. We recruited exclusively patients with normal cardiac function and HFpEF patients. Heart failure with reduced FEVS patients were excluded from the study. We have described for each patient the demographic and clinical characteristics, comorbidities, instrumental test results and clinical outcomes. In order to assess, for each group, the relationship between patient characteristics and clinical outcomes, the Chi-square test or alternatively the Pearson-Spearman correlation coefficients were calculated.
Results
the 194 patients studied had an average age of 73,7 years (min. 27, max 94). 59 AF patients had pre-existing HFpEF, whereas AF patients without HF were 67. Patients with pre-existing HFpEF and newly-onset AF had a more advanced age (76,7 y vs 72,9 y), and greater comorbidity (meanly 4 vs 3) rather than AF patients without HFpEF. Moreover, percentage of converting arrhythmia were significantly higher in AF patients without HFpEF. . Patients with acute PE and pre-existing HFpEF were 38, whereas PE patients without HF were 30. Acute PE patients with pre-existing HFpEF had older age, a prevalence for femal sex, more comorbidities, an average longer hospitalizations, but no significantly different rates of severe complications (ictus, hemorrhagies, needs for ventilation, pulmonary infarction or deaths) rather than PE patients without HFpEF.
Conclusions
the patients with AF or PE and concomitant HFpEF that were hospitalized from April 2017 to October 2020, showed an average longer hospitalization, a lower percentage of converting arrhythmia, probably due to the older age and the greater comorbidity.
