dilated cardiomyopathy heart failure :: Article Creator One Gene, Two Different Heart Diseases—new Study Shows Why gene, show such different symptoms. The research, led by Professor Stuart Campbell at Yale University, used lab-grown heart tissue to understand the differences between hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). The study was published in the Journal of Clinical Investigation. HCM and DCM are two of the most common inherited heart diseases. They can cause sudden death or heart failure, even in young and healthy people. HCM causes the walls of the heart's left ventricle to thicken, making it harder for the heart to pump blood. In contrast, DCM makes the heart walls thinner, which weakens the heart's ability to pump. Both diseases can be caused by changes (mutations) in the same gene that makes a protein called tropomyosin, which helps control how the heart muscle contracts. Campbell...

white coat syndrome heart rate :: Article Creator I Suffer From 'white Coat' Syndrome, But Not Like Other People I suffer from a strange medical syndrome. I've probably had it for most of my life. Still, I became aware of my syndrome only recently, when I felt a tingling in my lower legs. The tingling persisted over several weeks, and I booked in to see a neurologist. Brain doctors are very busy, so I had to wait several more weeks to see him. The tingling was incredibly annoying, and I longed for it to stop. My symptoms disappear when I see the doctor.Credit: iStock I was extremely relieved when the day of the appointment finally arrived. The neurologist took a thorough history, and then asked me to describe the tingling. I paused, and focussed on my legs. OK, I thought. That's weird. They felt completely normal. They hadn't felt normal yesterday, or any of the days before. I realised, with dismay, that the tingling ha...

pulmonic valve disease :: Article Creator Pulmonic Valve Stenosis Pulmonic valve stenosis occurs when the pulmonic valve is not able to open normally in systole. This results in right ventricular pressure overload, right ventricular hypertrophy and eventual right ventricular heart failure. The vast majority of cases of pulmonic valve stenosis are congenital. The symptoms include those of right heart failure predominantly dyspnea on exertion.Lower extremity dependant edema can occur and when the legs are elevated at night, the fluid redistributes centrally causing pulmonary edema resulting in orthopnea (dyspnea while laying flat) or paroxysmal nocturnal dyspnea (PND). Hepatic congestion can occur causing right upper quadrant abdominal pain. Physical Examination Findings of right heart failure can be seen upon physical examination including elevated jugular venous pressure, hepatojugular reflux and lowe...

congenital hypertension :: Article Creator In PAH, Main Pulmonary Artery Diameter Predicts Adverse Outcomes Main pulmonary artery (MPA) diameter is a prognostic indicator in patients with pulmonary arterial hypertension (PAH) without congenital heart disease, according to study findings published in Chest. Investigators characterized the size and growth of the MPA in patients with PAH without congenital heart disease. The researchers also assessed the prognostic value of MPA relative to existing risk stratification scores. A composite of all-cause mortality, lung transplantation, and hospitalization for right heart failure was the primary outcome. The study included patients from 2 pulmonary hypertension referral centers in Sydney, Australia, who had pulmonary artery imaging at least once between January 2010 and December 2021. Participants were identified through a retrospective review of electronic medical records of patients with PAH without ...

having high blood pressure :: Article Creator Haims: The Devastating Effects Of High Blood Pressure High blood pressure is often referred to as the "silent killer" for good reason. Too often, people have no idea they are at risk.  Most people over high school age are aware that high blood pressure is not a good thing, but many may not be aware of the specific health concerns that may develop, and the possible devastating consequences if left unaddressed. Elevated blood pressure may not only lead to heart disease, kidney diseases, neuropathy and stroke, but it has been linked to two of the most common causes of dementia, vascular cognitive impairment and Alzheimer's disease. A study by Johns Hopkins researchers showed that midlife hypertension raises the odds of cognitive issues as people age. Fortunately, when addressed early, risks may drop considerably. Between August 2021 and August 2023, data from the Centers for Disease ...
