Summary
The complement system plays a key role in various heart diseases, including coronary heart disease and heart failure. Understanding its exact role may lead to new therapeutic interventions for cardiac conditions.
Area of Science:
- Cardiology
- Immunology
- Inflammation
Background:
- Heart diseases are a leading cause of death globally.
- Complement-mediated inflammation is increasingly recognized in various cardiac conditions.
- Previous clinical trials with complement inhibitors yielded mixed results.
Purpose of the Study:
- To explore the association between the complement system and diverse heart diseases.
- To highlight the prognostic significance of complement activation in cardiovascular conditions.
- To identify potential therapeutic targets within the complement system for heart disease.
Main Methods:
- Review of emerging evidence on complement system involvement in cardiac pathophysiology.
- Analysis of studies linking complement activation to coronary heart disease, heart failure, and atrial fibrillation.
- Examination of the complement system's role in Chagas heart disease.
Main Results:
- The complement system is implicated in the pathophysiology of coronary heart disease, heart failure, and atrial fibrillation.
- Complement activation holds prognostic importance in heart failure.
- The complement system is crucial in the host-parasite interaction in Chagas heart disease.
Conclusions:
- Complement activation is involved in a wide spectrum of cardiac conditions.
- Further research is needed to elucidate the precise role of complement in different heart diseases.
- Identifying patients who could benefit from complement-targeted therapies is a key future direction.

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

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...

10.4K
The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a...

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...
