Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

Irregular bedtime could double the risk of serious cardiac events

An irregular bedtime in midlife may signal an increased risk of cardiovascular disease. A new study from the University of Oulu suggests that large swings in when people go to bed could double the risk of serious cardiac events—particularly among those who get less than eight hours of sleep.

Time-restricted eating improves hormone levels in women with PCOS

Polycystic ovary syndrome, or PCOS, affects as many as 18% of all childbearing-age women. The condition occurs when a woman's body produces too much of a group of hormones called androgens, chiefly testosterone. Menstrual irregularity, obesity and even infertility can result.

AI eye exams accurately identify heart disease risk during routine visits

A new system that uses artificial intelligence (AI) to assess cardiovascular risk based on images of the eye captured during eye exams demonstrated strong correlation with a standard cardiovascular risk assessment, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Triglyceride-lowering drug olezarsen fails to reduce arterial plaque

Despite experiencing significant reductions in triglycerides, patients with triglycerides over 150 mg/dL and a high risk of atherosclerosis did not experience any significant change in the amount of non-calcified plaque in their coronary arteries after taking the triglyceride-lowering drug olezarsen, in a one-year sub-study presented at the American College of Cardiology's Annual Scientific Session.

Culturally tailored food programs significantly lower blood pressure in minority adults

Black and Hispanic adults with high blood pressure (hypertension) who received a culturally tailored food-based intervention with dietitian coaching experienced a significant drop in blood pressure compared with those who received an equivalent amount of fresh produce without additional supports, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Digoxin found safe to use in young patients with rheumatic heart disease

Patients with rheumatic heart disease who took the heart failure drug digoxin were 18% less likely to die or experience new-onset or worsening heart failure during a two-year follow-up compared with those who received a placebo, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Discontinuing beta-blockers after heart attack found to be safe for low-risk patients

Among stable, relatively low-risk patients who had previously suffered a heart attack, discontinuing beta-blockers after at least one year was found to be non-inferior, or comparable, to continuing beta-blockers in terms of death, another heart attack or hospitalization for heart failure, according to a study presented at the American College of Cardiology's Annual Scientific Session.

New clinical guideline adopts holistic approach to brain and heart health

A new brain–heart clinical practice guideline takes a holistic approach, integrating neurologic and mental health evidence with guidance for cardiovascular disease as many brain and heart conditions overlap and share similar risk factors.

Taking a placebo knowingly still improves stress and memory

Research indicates open-label placebos can ease stress and boost memory in older adults, presenting a novel, ethical strategy for promoting healthy aging.

Short bursts of vigorous activity can lower risk of major diseases

People who get just a few minutes of vigorous activity daily are less likely to develop eight major diseases, including arthritis, heart disease and dementia, according to research published in the European Heart Journal today (Monday).

Deferring PCI before TAVR shows comparable outcomes in elderly patients

Older patients with coronary artery disease scheduled for transcatheter aortic valve replacement (TAVR) had comparable outcomes regardless of whether they underwent percutaneous coronary intervention (PCI) before TAVR, according to findings from the PRO-TAVI study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Transcatheter valve-in-valve procedure improves short-term outcomes in high-risk patients

In patients with a poorly functioning bioprosthetic mitral valve in the heart, a minimally invasive procedure to insert a new valve was associated with a lower rate of death or disabling stroke within one year, compared with patients who underwent standard repeat mitral valve replacement surgery, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Minimally invasive valve repair lowers hospitalizations in heart failure patients

At two years of follow-up, patients with a poorly functioning tricuspid valve in the heart who received optimal medical therapy plus a minimally invasive procedure using a clip to repair the valve were significantly less likely to die, have a heart attack or stroke and 40% less likely to be hospitalized for heart failure compared with similar patients who were randomly assigned to optimal medical therapy alone.

New drug sotatercept shows benefit in CpcPH-HFpEF patients

Patients who have heart failure with preserved ejection fraction (HFpEF) and high blood pressure in the lungs (pulmonary hypertension) experienced significant improvements in blood pressure and vascular health after taking the drug sotatercept, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Noninvasive lung impedance monitoring improves outcomes in HFpEF patients

Treatment management guided by the use of a noninvasive device to monitor fluid accumulation in the lungs substantially reduced hospitalizations and deaths among patients with heart failure with preserved ejection fraction (HFpEF), according to research presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Trial shows mavacamten benefits adolescents with obstructive heart condition

Adolescent patients with obstructive hypertrophic cardiomyopathy (HCM) who received the drug mavacamten saw a significant improvement in left ventricular outflow tract (LVOT) gradient, a measure of blood flow obstruction in the heart, compared with those who received a placebo, according to a small study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Left-ventricular unloading during angioplasty fails to improve patient outcomes

The first randomized trial to compare standard percutaneous coronary intervention (PCI), also known as coronary angioplasty, with PCI accompanied by the use of a temporary, miniaturized pump to support the heart in patients with both severe coronary heart disease and moderate to severe heart failure found no significant difference between the two approaches.
