Summary
Patients with heart failure-related cardiogenic shock (HF-CS) were younger and had lower mortality rates than those with acute myocardial infarction-related cardiogenic shock (AMI-CS). Both groups experienced similar high rates of readmission and adverse events, requiring close long-term monitoring.
Area of Science:
- Cardiology
- Critical Care Medicine
- Health Outcomes Research
Background:
- Clinical characteristics and outcomes of heart failure-related cardiogenic shock (HF-CS) are poorly understood compared to acute myocardial infarction-related cardiogenic shock (AMI-CS).
- Understanding these differences is crucial for optimizing patient care and improving prognoses in cardiogenic shock.
Purpose of the Study:
- To compare the clinical features, hospital course, and 1-year outcomes of patients with HF-CS versus AMI-CS.
- To identify disparities in treatment and survival between these two patient populations.
Main Methods:
- A single-center registry study included 520 consecutive patients with cardiogenic shock (CS) from January 2017 to December 2019.
- In-hospital and 1-year outcomes were analyzed, comparing patients with HF-CS (n=301) to those with AMI-CS (n=219).
Main Results:
- HF-CS patients were younger, utilized fewer vasopressors, and had lower in-hospital mortality (23.9% vs 39.3%) compared to AMI-CS patients.
- Despite lower mortality, HF-CS patients had similar 30-day readmission rates and major adverse cardiac and cerebrovascular events (MACCE) post-discharge.
- 1-year mortality was significantly lower in HF-CS patients (42.6%) than in AMI-CS patients (52.9%).
Conclusions:
- Patients with HF-CS present differently and have better in-hospital and 1-year survival than those with AMI-CS.
- Both HF-CS and AMI-CS cohorts face substantial risks for adverse events and readmissions, necessitating comprehensive long-term follow-up strategies.

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...

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

1.9K
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...

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...
