Abstract

Abstract: Introduction: Frailty studies focused on patients with infective endocarditis (IE) are scarce and its potential impact on patient outcomes is not well known. The aim of this study is to describe the clinical profile and prognosis of elderly patients with IE, comparing patients who met the frailty criteria versus those who did not. Methods: A total of 121 cases of confirmed IE were consecutively collected in three tertiary hospitals between 2017 and 2019. The patients were classified into two groups: Group I (n=49), patients with IE who met the Frail criteria for frailty, and Group II (n=72), those patients without frailty by this scale. Results: The median age of our cohort was 77 years (69–82), and 62.8% were men. Frail patients were older than those in Group II, as shown in Table 1. Regarding comorbidity, chronic anemia (40.8% vs 25%; p<0.060) was more common in Group I, as well as rheumatic manifestations at admission (12.2% vs 1.4%; p=0.014). The most frequently isolated microorganisms were S. aureus (n=25), coagulase negative staphylococci (n=25), viridans group streptococci (n=14), and enterococci (n=14). Enterococci (16.3% vs 8.3%, p=0.177) and non-viridans streptococci (10.2% vs 2.8%); p=0.086) were more frequent in frail patients. Vegetation (79.6% vs 80.6%; p=0.896) and periannular complications (24.5% vs 29.2%; p=0.571) were similar in both groups. No significant differences were found regarding the location of the infection. The incidence of in-hospital complications was similar between both groups. Frail patients underwent surgery less frequently than those in Group II, and had higher predicted mortality on surgical risk scale scores. However, the percentage of patients who met the surgical criteria and were considered inoperable was similar (33.3% vs 26.2%; p=0.415). In-hospital mortality was similar in both groups. When analyzing in-hospital mortality according to the therapeutic strategy in Group I, a mortality of 34.5% was observed in frail patients with conservative medical treatment, compared to 47.1% in those patients who underwent surgery in the same group. One third of our patients received outpatient antibiotic treatment, being significantly more frequent in Group I (39.6% vs 29.0%; p=0.232). Conclusions: The elderly patients with IE and frailty criteria were older and more frequently had rheumatic symptoms at admission. Enterococci and non-viridans streptococci were isolated more frequently than in non-frailty patients. Surgery was less performed among frail patients, who had a higher predicted surgical risk. Although complications and in-hospital mortality were similar between both groups, in the group of frail patients, those with conservative management showed lower mortality compared to surgery.
