Summary
Hospital readmission and mortality rates for heart failure (HF) patients remain high globally. International variations in HF readmission were not explained by healthcare spending or patient comorbidities.
Area of Science:
- Cardiology
- Public Health
- Health Services Research
Background:
- International comparisons of heart failure (HF) readmission rates are lacking.
- Understanding global variations in HF outcomes can inform patient management strategies.
- Previous studies have not comprehensively analyzed international HF readmission and mortality data.
Approach:
- Systematic review and meta-analysis of observational studies on hospitalized adult HF patients.
- Included studies published between January 2010 and March 2021, sourced from MEDLINE, Embase, and CENTRAL.
- Utilized a random-effects model for meta-analysis of proportions and meta-regression to explore heterogeneity.
Key Points:
- Analyzed 24 papers for 30-day and 23 for 1-year readmission, involving 1.5 million individuals.
- 30-day readmission rate was 13.2% (95% CI: 10.5%-16.1%); 1-year rate was 35.7% (95% CI: 27.1%-44.9%).
- 30-day mortality was 7.6% (95% CI: 6.1%-9.3%); 1-year mortality was 23.3% (95% CI: 20.8%-25.9%).
Conclusions:
- Hospitalized heart failure patients face high global readmission and mortality rates.
- Significant international variability in HF readmission rates exists.
- This variability could not be explained by healthcare expenditure, mortality risk, or comorbidities.

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

01:27Heart Failure I: Introduction
18
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

01:22Heart Failure Drugs: β-Blockers
364
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...
