Where can I Auscultate my S4?
A fourth heart sound arising from the right ventricle is best heard with the bell of the stethoscope placed at the lower left sternal border or subxiphoid area.

S1 Heart Sound | S2 Heart Sound | S3 Heart Sound | S4 Heart Sound | Extra Heart Sounds.
Can MI lead to heart failure?
Myocardial infarction (MI) remains the most common cause of heart failure (HF) worldwide. For almost 50 years HF has been recognised as a determinant of adverse prognosis after MI, but efforts to promote myocardial repair have failed to translate into clinical therapies.
Can sepsis cause myocarditis?
Acute sepsis decreases cardiac contractility and impairs myocardial compliance. Chronic inflammation such as that occurring in Duchenne muscular dystropshy and myocarditis may cause adverse cardiac remodeling including myocyte hypertrophy and death, fibrosis, and altered myocyte function.
What is S4 in heart sounds?
The fourth heart sound (S4), also known as the “atrial gallop,” occurs just before S1 when the atria contract to force blood into the left ventricle. If the left ventricle is noncompliant, and atrial contraction forces blood through the atrioventricular valves, a S4 is produced by the blood striking the left ventricle.

How does MI cause left heart failure?
It produces both a vasculopathy and left ventricular dysfunction and fibrosis. Endothelial dysfunction in the coronary arteries can lead to acute coronary events. Left ventricular dysfunction will cause the progression of heart failure, and left ventricular fibrosis and dysfunction provide an arrhythmic substrate.
Does Mi cause left ventricular failure?
Background: Multiple sclerosis (MS) can affect cardiovascular function in a variety of ways leading to abnormalities in blood pressure response, heart rate, heart rhythm, left ventricular systolic function, and may cause pulmonary edema or cardiomyopathy.
What virus causes CHF?
Although the most common result of a coxsackievirus infection is the flu, they can also cause pancreatitis leading to diabetes, arthritis, meningitis and myocarditis (an infection of the heart muscle) leading to heart failure.
