Summary
Cardio-renal syndrome type 1 (CRS1) is a common complication following ST-segment elevation myocardial infarction (STEMI). Key risk factors include age, diabetes, and reduced heart function, while timely revascularization may lower CRS1 incidence.
Area of Science:
- Cardiology
- Nephrology
- Internal Medicine
Background:
- ST-segment elevation myocardial infarction (STEMI) frequently leads to cardio-renal syndrome type 1 (CRS1).
- Understanding CRS1 risk factors is crucial for patient management post-STEMI.
Purpose of the Study:
- To identify independent risk factors for developing CRS1 after STEMI.
- To assess the impact of emergency percutaneous coronary intervention (PCI) on CRS1 incidence.
Main Methods:
- A cohort of 378 STEMI patients were categorized into CRS1 (n=98) and non-CRS1 (n=280) groups.
- Clinical characteristics were compared, and multivariate logistic regression identified independent risk factors.
- The effect of emergency PCI on CRS1 was evaluated in a subgroup of patients.
Main Results:
- CRS1 occurred in 25.9% of STEMI patients.
- Independent risk factors for CRS1 included older age, diabetes history, higher systolic blood pressure, severe Killip classification, reduced left ventricular ejection fraction, lower eGFR, not undergoing emergency PCI, and not using ACEI/ARB.
- In patients undergoing emergency PCI, higher door-to-balloon time and contrast agent volume were associated with CRS1.
Conclusions:
- CRS1 is a frequent complication of STEMI, influenced by multiple clinical factors.
- Prompt revascularization through emergency PCI appears to mitigate CRS1 development in STEMI patients.

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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...

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...
