The purpose of the EARLY study is to evaluate the efficacy and effectiveness of early surgery in patients with Infective Endocarditis (IE).
Infective endocarditis (IE) is a relatively rare disease and has a high in-hospital mortality (15-30%) and morbidity due to complications like embolic events, especially in the central nervous system, and heart failure. International guidelines give indications on the optimal timing for surgery, and they strongly recommend early surgery for patients in the active phase of IE with acute cardiac complications (e.g., acute heart failure, uncontrolled infection, and persistent large vegetations after an embolic event). However, at present there is no clear evidence supporting the effectiveness of early surgery or indicating the best time to perform surgery, especially in patients without such conditions. Primary objective of the study is to evaluate whether, in patients with IE and no emergency surgery indication, an early surgical strategy (performed within 72 hours from IE diagnosis) is more effective than conventional therapy in terms of 1-year stroke-free survival. Secondary objectives are: overall survival, risk of embolic, risk of strokes, event-free survival, IE relapse, heart failure, length of hospital stay, hospital re-admission and hospitalization days, strategy compliance, quality of life and health care costs.
This study design consist of a two-arm, open-label, multicenter randomized controlled trial, but patients who decline to be randomized and prefer a certain therapy strategy will be treated according to best practice and included into a prospective observational study after given informed consent. This parallel constructed observational study will be performed with a maximum of consistency to treatment and observation compared to the Randomized clinical trial (RCT). Patients who agree to the randomized trial will be stratified according to centre and clinical features (prosthetic valve,vegetations, valve regurgitation) and randomized with a 1: 1 ratio to 2 different strategies.
According to O'Brien and Fleming group sequential design with a maximum of two stages and a drop-out rate of 10%, a total of 400 randomized patients (200 per group) are required to detect an increase in the stroke-free survival from 82% to 89.5% (corresponding to an Hazard Ratio=0.56) considering a significance level of 5% and a power of 80% and expecting a risk for mortality or stroke at one year with standard treatment equal to 0.18.
EARLY study may help to demonstrate early surgery impact on the contemporary management of the disease.

Heart failure during the hospitalization of IE diagnosis
Proportion of patients with diagnosis of Heart failure during the hospitalization of IE diagnosis.
Time frame: During follow-up, until discharge from hospital, up to 1 year from randomization date
Cumulative incidence of stroke
Probability that a patient will have a stroke at 12 months from randomization assuming they do not die from some other cause.
Time frame: 12 months
Cumulative incidence of embolic events
Probability that a patient will have an embolic events at 12 months from randomization assuming they do not die from some other cause.
Time frame: 12 months
Cumulative incidence of heart failure
Probability that a patients will have a heart failure at 12 months from randomization assuming they do not die from some other cause.
Time frame: 12 months
Cumulative incidence of IE relapse
Probability that a patient will have an IE relapse at 12 months from randomization assuming they do not die from some other cause.
Time frame: 12 months
Quality of Life using 36-Item Short Form Survey (SF-36)
SF-36 is a generic 36-item questionnaire measuring health-related quality of life (HRQL) composed by 8 subscales. Participants self-report on items that have between 2-6 choices per item using Likert-type responses. Summations of item scores of the same subscale give the subscale scores. Two composite scores, physical component summary (PCS) and mental component summary (MCS), can be derived by a linear combination of the 8 subscales. The PCS is represented by 4 subscales: physical function, role limitations due to physical problems, pain, and general health perception. The MCS is represented by 4 subscales: vitality, social function, role limitations due to emotional problems, and mental health. Both subscales and composite scores are transformed into a range from 0 to 100; zero= worst HRQL, 100=best HRQL.
Time frame: 0, 4, 12 months
Quality of Life using EuroQol five dimension (EQ-5D).
Quality of life will be evaluated using EuroQol five dimension (EQ-5D), a patient-completed, multidimensional measure of health related quality of life. The instrument is applicable to a wide range of health conditions and treatments and results in a single index score. The EQ-5D descriptive health profile comprises five dimensions of health (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). Each dimension comprises three levels (no problems, some/moderate problems, extreme problems). A unique EQ-5D health state is defined by combining one level from each of the five dimensions. EQ-5D index values range from -0.38 to 1.00 (Italian utility weights). Higher EQ-5D Index scores represent better health status.
Time frame: 0, 4, 12 months
1-year event-free survival
Time from randomization until the first occurrence of one of the following event: , embolic event, IE relapse and heart failure or death.
Time frame: 12 months
Cost-effectiveness
Incremental cost-effectiveness ratio calculated as the ratio between difference in costs and difference in Quality Adjusted Life Years, from EQ-5D (QALYs) among the treatment groups, during the first year after randomization
Time frame: 12 months
Length of hospitalization
Number of days from the date of the randomization and the discharge date
Time frame: During follow-up, until discharge from hospital, up to 1 year from randomization date
Number of hospital readmission for length .of stay within 1 year for any cause
Number of days of hospitalization for any cause from the the date of discharge
Time frame: 12 months
Feasibility of early surgery
Ratio between the number of patients randomized to early surgery arm and operated within 72 hours and the number of patients randomized to early surgery arm
Time frame: During follow-up, until discharge from hospital, up to 1 year from randomization date
