Researchers pinpointed the DCHS1 gene as responsible for the most common form of mitral valve prolapse, a condition that leads to heart failure. The gene disrupts heart valve development and growth, causing structural integrity issues in the mitral valve.
A new consensus report highlights massive underdiagnosis and undertreatment of hereditary high blood cholesterol in virtually all countries, with the exception of Netherlands and Norway. Easy to diagnose through a blood test and family history, the condition can be treated with statins and a low-cholesterol diet.
A study found that combining high-intensity interval training with Mediterranean diet counselling significantly improves body fat mass, cholesterol levels, blood pressure, and weight loss in obese individuals. The intervention also resulted in improved aerobic fitness, reduced waist circumference, and better control of blood sugar levels.
A new study found that overnight dialysis boosts kidney health and reduces the risk of heart disease by improving artery function. This treatment method allows for more frequent and longer dialysis sessions at home, leading to reduced toxin buildup in the blood.

A CDC study links short and long sleep durations to increased risk of coronary heart disease, stroke, and diabetes. Adults 45+ who sleep six hours or less or more than 10 hours per night are at higher risk for these chronic diseases, the American Academy of Sleep Medicine advises.
A recent study published in Nature reveals that high blood sugar levels can cause irregular heartbeats, or cardiac arrhythmia, by activating a protein called CaMKII. The researchers found that O-GlcNAc, a sugar molecule, attaches to CaMKII and causes it to become overactive, leading to pathological changes in the heart's calcium signal...
The World Heart Federation is publishing a special issue to raise awareness about rheumatic heart disease (RHD), which is highly preventable but remains neglected globally. The special issue explores the burden of RHD, current challenges, and innovative solutions for prevention and treatment.
Treating strep throat with penicillin can reduce ARF/RHD risk by 70-80%, and including primary prevention in overall strategy is crucial. Global efforts to combat RHD control have shown success through comprehensive strategies involving syndromic treatment, education, and awareness campaigns.
Current estimates of rheumatic heart disease deaths globally are likely underestimates, with new studies underway to address data gaps and inform control strategies. The authors propose re-evaluating the burden of disease in two categories: symptomatic and asymptomatic disease.

A study found that echocardiographic screening in the general public for structural and valvular heart disease was not associated with a reduction in risk of death, myocardial infarction (heart attack) or stroke. Despite low prevalence of structural heart disease, screening led to unnecessary tests and potential harm.
A study of 26,902 male health professionals found that skipping breakfast was associated with a 27% increased risk of heart attack or death from coronary heart disease. Men who reported eating late at night also had a higher risk of coronary heart disease, but this may not be a major public health concern due to low prevalence in the s...

A study published in Chemical Research in Toxicology reveals that cigarette smoke affects key genes protecting the heart and lungs, leading to increased risk of heart disease in obese smokers. Cigarette smoke exposure also amplifies this effect in non-smoking obese individuals who inhale second-hand smoke.
Individuals with abdominal fat are at greater risk of heart disease and cancer compared to those with a similar BMI who carry their fat in other areas. The study used CT scans to assess ectopic fat locations around the heart tissue and aortic artery.
A study published in JAMA found that low vitamin D blood levels are associated with a greater risk of heart disease in whites and Chinese populations, but not in blacks and Hispanics. The researchers suggest that genetic factors may play a role in the varying associations between vitamin D levels and heart disease across different raci...
A new report by George Washington University researchers finds that many Medicaid beneficiaries lack access to essential preventive services. The study highlights gaps in coverage for critical services such as screening tests for colorectal cancer, high blood cholesterol, HIV infection, and diet counseling for obesity prevention.
Researchers at Duke University Medical Center developed a blood-based test that accurately identifies who will respond to aspirin therapy and predicts patients at risk for heart attacks. The test, known as the 'aspirin response signature,' measures gene activity patterns in the blood.
A new study conducted by Indiana University found that postmenopausal women who quit smoking reduced their risk of heart disease, with benefits starting to show within years. The study analyzed data from 104,391 women ages 50-79 and found a significant drop in heart disease risk among those who quit smoking, regardless of diabetes status.
Researchers found that simultaneously controlling high blood pressure and cholesterol can significantly reduce the risk of heart disease. The study suggests that prescribing medications and regular doctor visits can greatly benefit certain populations, including older adults and Hispanic-Americans.

Death rates from heart disease have decreased in most EU countries since the early 1980s, but some nations are experiencing a slowdown in progress due to rising obesity and diabetes rates. The study found that cardiovascular disease remains a leading cause of death in Europe, with significant variation between individual countries.
Patients with paroxysmal atrial fibrillation (AF) show signs of depression, sleeping disorders, and low levels of physical activity, despite physicians rating their quality of life higher. Good communication between physicians and patients is crucial for adherence to medications and long-term prognosis.
Research reveals a gene called CPT1A, which regulates fat breakdown in the liver, may increase risk of heart disease when methylated. The study found elevated levels of bad cholesterol and triglycerides, and lower adiponectin levels in patients with this genetic switch turned off.
A new study by Dr. Nav Persaud found a significant association between poor eating habits in kids ages three to five and their levels of non-HDL cholesterol, putting them at risk for cardiovascular disease later in life. Parents who allowed their children to snack on junk food and eat while watching TV were more likely to have this risk.
A recent clinical trial has found that impaired heart function among obese children and adolescents is associated with an increased risk of future heart disease.
