The burden of atrial fibrillation and heart failure in hospitalized patients: A real-world survey in a nationwide snapshot.

PURPOSE: Atrial fibrillation (AF) and heart failure (HF) are common and commonly coexisting cardiovascular diseases in hospitalized patients. We report the absolute number and interrelation between AF and HF, assess the daily burden of both diseases on the healthcare system, and describe the medical treatment in a real-world, nationwide conducted snapshot survey. METHODS: A questionnaire was equally distributed to various healthcare institutions. Data on the baseline characteristics, prior hospitalizations, and medical treatments of all hospitalized patients with AF and HF at a predefined date were collected and analyzed. RESULTS: Seventy-five cardiological departments participated in this multicenter Greek nationwide study. A total of 603 patients (mean age, 74.5 ± 11.4 years) with AF, HF, or the combination of both were nationwide admitted. AF, HF, and the combination of both were registered in 122 (20.2%), 196 (32.5%), and 285 (47.3%) patients, respectively. First-time hospital admission was recorded in 273 (45.7%) of 597 patients, whereas 324 (54.3%) of 597 patients had readmissions in the past 12 months. Of the entire population, 453 (75.1%) were on beta-blockers (BBs), and 430 (71.3%) were on loop diuretics. Furthermore, 315 patients with AF (77.4%) were on oral anticoagulation, of whom 191 (46.9%) were on a direct oral anticoagulant and 124 (30.5%) were on a vitamin K antagonist. CONCLUSION: Hospitalized patients with AF and/or HF have more than one admission within a year. Coexistence of AF and HF is more common. BBs and loop diuretics are the most commonly used drugs. More than three-quarters of the patients with AF were on oral anticoagulation.

Long-term risk, clinical management, and healthcare resource utilization of stable patients with coronary artery disease and post-myocardial infarction in Greece - TIGREECE study.

BACKGROUND: In light of the scarcity of evidence, TIGREECE evaluated the clinical management and long-term outcomes of patients at high risk for an atherothrombotic event who have suffered a myocardial infarction (MI), managed by cardiologists/internists in routine hospital and private office settings in Greece. METHODS: TIGREECE, a multicenter, 3-year prospective cohort study, enrolled patients ≥50 years old, with a history of MI 1-3 years before enrollment and with at least one of the following risk factors: age ≥65 years, diabetes mellitus requiring medication, second prior MI, multivessel coronary artery disease, and creatinine clearance 15-60 mL/min. The primary outcome was a composite of MI, unstable angina with urgent revascularization, stroke, or all-cause death. RESULTS: Between 5 June 2014 and 25 July 2015, 305 eligible consented patients (median age: 67.3 years; 81.3% males; 14.8% active smokers; 80.7% overweight/obese) were enrolled; 52.5% had ≥2 qualifying risk factors. The median time from the index MI [ST-segment elevation myocardial infarction (STEMI) in 51.1%, non-STEMI in 33.1%] to enrollment was 1.7 years. Of the patients, 65.9% had been discharged on dual antiplatelet therapy. At enrollment, 94.4% were receiving antiplatelets: 60.0% single [acetylsalicylic acid (ASA): 43.3%; clopidogrel: 15.7%] and 34.4% dual (ASA + clopidogrel: 31.8%) therapy. The Kaplan-Meier estimated 3-year primary composite event rate was 9.3% [95% confidence interval (CI): 6.4-13.0), and the ischemic composite event rate was 6.7% (95% CI: 4.2-9.9). CONCLUSIONS: Study results indicate that in the routine care of Greece one in ten patients experience a recurring cardiovascular event or death, mainly of ischemic origin, 1-3 years post-MI.
