Abstract ; Background : One of the major determinants of exercise intolerance and limiting symptoms among patients with obstructive hypertrophic cardiomyopathy (HCM) is an elevated intracardiac pressure resulting from left ventricular outflow tract obstruction. Aficamten is an oral selective cardiac myosin inhibitor that reduces left ventricular outflow tract gradients by mitigating cardiac hypercontractility. Results : A total of 282 patients underwent randomization: 142 to the aficamten group ...

Hypertrophic cardiomyopathy (HCM) is a disease that involves the thickening of your heart muscle. Most people with HCM can live a normal life. Treatments are available.
WASHINGTON and DALLAS, May 8, 2024 — The American College of Cardiology (ACC) and the American Heart Association (AHA) today released a new clinical guideline for effectively managing individuals diagnosed with hypertrophic cardiomyopathy (HCM). The guideline reiterates the importance of collaborative decision-making with patients who have HCM and provides updated recommendations for the most effective treatment pathways for adult and pediatric patients. HCM is an inherited cardiac condition most often caused by a gene mutation that makes the ...
Diagnosis ; Echocardiogram. An echocardiogram often is used to diagnose hypertrophic cardiomyopathy. Sound waves are used to create images of the beating heart. This test shows how well the heart's chambers and valves are pumping blood. An echocardiogram also can see if the heart's muscle is thicker than it should be. Beta blockers such as metoprolol (Lopressor, Toprol-XL), propranolol (Inderal LA, Innopran XL) or atenolol (Tenormin). Exercise. Ask your healthcare professional about the amount a...
Hypertrophic cardiomyopathy (HCM) is an autosomal dominant cardiac myocyte disease caused by mutations in sarcomere and sarcomere-related protein genes encoding for elements of the contractile mach...
Overview ; Hypertrophic cardiomyopathy usually is caused by changes in genes that cause the heart muscle to thicken. Hypertrophic cardiomyopathy typically affects the wall between the two bottom chambers of the heart. This wall is called the septum. The chambers are called the ventricles. The thickened wall might block blood flow out of the heart. This is called obstructive hypertrophic cardiomyopathy. If there's no significant blocking of blood flow, the condition is called nonobstructive hyper...
Hypertrophic cardiomyopathy (HCM) can be a scary diagnosis. There’s no cure for HCM, which causes the muscles in your heart to thicken and stiffen, leading to the obstruction of blood flow to your ticker, scar tissue buildup, and a higher risk of stroke and heart attack. A small number of people with HCM will develop heart failure. And in rare cases, the disease can trigger sudden cardiac arrest, which is quickly fatal if not immediately treated. What’s more, this condition can get worse ove...
Hypertrophic cardiomyopathy (HCM) is the most common heritable cardiomyopathy, yet pharmacological therapy has been unchanged for decades until the recent introduction of mavacamten, a first-in-cla...
