Summary
Spontaneous coronary artery dissection (SCAD) is linked to fibromuscular dysplasia (FMD). Screening all SCAD patients for FMD is recommended, with a focus on diagnosis and management strategies.
Area of Science:
- Cardiology
- Vascular Medicine
- Radiology
Background:
- Spontaneous coronary artery dissection (SCAD) is a growing cause of acute coronary syndromes.
- Fibromuscular dysplasia (FMD) is a nonatherosclerotic arterial disease causing dissections, stenosis, and aneurysms.
- Extracoronary FMD is found in about 70% of SCAD patients.
Purpose of the Study:
- To review current diagnostic and management approaches for patients with FMD.
- To emphasize the importance of FMD screening in SCAD patients.
Main Methods:
- Literature review of SCAD and FMD diagnosis and management.
- Highlighting computed tomography angiography (CTA) for FMD screening.
Main Results:
- Extracoronary FMD is prevalent in SCAD patients (approx. 70%).
- Lifetime screening for FMD in SCAD patients is advised.
Conclusions:
- Cardiologists should be aware of the FMD-SCAD connection.
- Comprehensive screening and management of FMD are crucial for SCAD patients.

1.2K
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...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

01:27Mitral Valve Prolapse I: Introduction
4
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

01:22Mitral Stenosis I: Introduction
2
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

01:17Pathophysiology of Heart Failure
1.5K
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...
