Scientists discovered that fasting may help reverse heart damage caused by a specific genetic mutation in the PLN gene called R14del. This mutation causes a common type of inherited heart disease where abnormal protein clumps build up in heart cells. The research shows that fasting activates the cell's cleanup system (lysosomes) to remove these harmful clumps and restore heart function.
WHY IT MATTERSIf confirmed in human studies, fasting could offer PLN R14del cardiomyopathy patients a non-drug intervention to potentially reverse heart damage, though this is currently only demonstrated in laboratory research and requires clinical validation.

A patient with ATTR-CM (a rare heart disease caused by abnormal protein buildup) is sharing their experience saying goodbye to a doctor who understood their condition deeply. When you have a rare disease, finding a doctor who takes time to learn your personal story and medical history is especially valuable. This article highlights how important that doctor-patient relationship is for people managing uncommon health conditions.
WHY IT MATTERSFor ATTR-CM patients, continuity of care with a knowledgeable physician directly impacts treatment decisions and quality of life, making transitions to new doctors particularly challenging.

ATTR-CM is a rare heart disease caused by abnormal protein buildup, but many patients also experience serious stomach and digestive problems that doctors don't always talk about. These gastrointestinal issues—like difficulty swallowing, nausea, and poor nutrient absorption—can be just as challenging as the heart symptoms and significantly impact quality of life. The article highlights that patients need better awareness and support for managing these hidden digestive complications alongside their heart treatment.
WHY IT MATTERSATTR-CM patients often suffer from overlooked gastrointestinal complications that can worsen malnutrition and quality of life, yet these symptoms receive less medical attention than cardiac manifestations—understanding this connection helps patients advocate for comprehensive care.

This article discusses rare diseases that affect the major blood vessels in the neck and upper chest (called supra-aortic trunks). While most blockages in these vessels are caused by common heart disease risk factors, about 10% happen in people without those risk factors. The article highlights three newly recognized conditions: TIPIC syndrome (temporary inflammation around the carotid artery), carotid web (an unusual narrowing), and Eagle syndrome (a bone growth problem). Better imaging technology is helping doctors identify these rare conditions more accurately.
WHY IT MATTERSIf you have unexplained neck pain, stroke symptoms, or carotid artery narrowing without typical heart disease risk factors, your doctor may now consider these emerging diagnoses instead of assuming standard atherosclerosis.

Researchers at the National Heart, Lung, and Blood Institute are looking for 5,000 people who have or might have diseases that affect their heart, blood vessels, or metabolism. Participants will have blood tests and heart function tests tailored to their specific condition. Both people with these conditions and healthy people can join to help scientists understand why some people develop heart disease.
WHY IT MATTERSThis large-scale study is actively recruiting and may help identify new risk factors for heart disease in people with rare metabolic, inflammatory, and genetic conditions like Li-Fraumeni Syndrome and cardiomyopathy.
