Insights

The COVID-19 pandemic significantly reduced acute heart failure (AHF) hospital admissions and altered patient referral patterns. In-hospital mortality for AHF patients increased, especially those with concurrent COVID-19.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic profoundly impacted global healthcare delivery systems.
  • Understanding its effects on acute heart failure (AHF) patient management is crucial.

Purpose of the Study:

  • To evaluate the influence of the COVID-19 pandemic on hospital admissions for AHF.
  • To assess changes in in-hospital mortality rates among AHF patients during the pandemic.

Main Methods:

  • Retrospective, multicentre study analyzing data from 24 Cardiology Departments in Poland.
  • Involved a total of 101,433 hospitalizations between January 1, 2019, and December 31, 2020.
  • Compared AHF patient admissions, referral methods, length of stay, and mortality rates pre-pandemic and during the pandemic.

Main Results:

  • AHF hospital admissions decreased by 23.4% in 2020 compared to 2019.
  • A significant reduction in self-referrals (27.8%) and an increase in ambulance-brought AHF patients (15.9%) were observed.
  • In-hospital mortality for AHF patients rose from 5.2% in 2019 to 6.5% in 2020 (P < 0.001).
  • Among AHF patients hospitalized in 2020, 3.2% had concomitant COVID-19, with an extremely high in-hospital mortality rate of 31.4%.

Conclusions:

  • The COVID-19 pandemic led to fewer hospital admissions for AHF.
  • Patient presentation shifted towards ambulance transport, with fewer self-referrals.
  • In-hospital mortality for AHF patients increased, particularly for those co-infected with COVID-19, highlighting a critical public health concern.

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Heart Failure II: Pathophysiology

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...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

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...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Heart Failure I: Introduction01:27

Heart Failure I: Introduction

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...
