Summary
Transferring patients with cardiogenic shock (CS) to hospitals with 24-hour coronary angiography and higher annual CS volume significantly reduces 30-day mortality. These findings support regionalized care systems for improved CS patient outcomes.
Area of Science:
- Cardiology
- Emergency Medicine
- Health Systems Research
Background:
- Regionalized systems of care are increasingly used for cardiogenic shock (CS) management.
- Hospital characteristics may influence outcomes for CS patients transferred by emergency medical services (EMS).
Purpose of the Study:
- To assess if receiving hospital characteristics influence outcomes in CS patients transferred by EMS.
- Key characteristics examined include 24-hour coronary angiography, on-site cardiac surgery, and annual CS treatment volume.
Main Methods:
- Population-based cohort study of adult CS patients transferred by EMS in Victoria, Australia (2015-2019).
- Data linked from ambulance, hospital, and death index records.
- Primary outcome: 30-day mortality, stratified by receiving hospital capabilities.
Main Results:
- EMS transfer to a cardiac center with 24-hour angiography reduced 30-day mortality (aOR 0.78).
- Hospitals with higher annual CS volume (>55 cases/year) showed reduced 30-day mortality risk (aOR 0.71).
- Stepwise reduction in mortality observed for patients transferred to trauma level 1 centers compared to other cardiac centers.
Conclusions:
- Receiving hospital characteristics significantly impact survival outcomes for CS patients.
- Findings emphasize the importance of hospital capabilities in regionalized CS care systems for EMS-transferred patients.

01:26Heart Failure III: Clinical Manifestations
39
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...

1.8K
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...

Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

01:27Heart Failure I: Introduction
45
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...

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...

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
