Fixed-dose combination therapy provides better results than monotherapy for pulmonary hypertension

Patients with pulmonary arterial hypertension (high blood pressure in the arteries that supply the lungs, also called PAH) had approximately double the reduction in pulmonary vascular resistance (PVR) if they took the PAH medications macitentan (10 mg) and tadalafil (40 mg) together in a single tablet rather than either drug alone, according to research being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

People with atopy have lower prevalence of cancers in extracutaneous sites and reduced melanoma risk

Fewer cases of melanoma were observed in people with a history of atopic diseases, such as allergic asthma or rhinitis, than in nonatopic people.

Trial emulation shows the effectiveness of the COVID-19 vaccine in improving long COVID symptoms

In a recent article published in the BMJ, researchers evaluated the effect of coronavirus disease 2019 (COVID-19) vaccines on patients with long COVID.

Meta-analysis on COVID-19 vaccine effectiveness in association with antibody titers

Researchers performed a meta-analysis analyzing randomized controlled trials (RCTs) that evaluated the effectiveness of coronavirus disease 2019 (COVID-19) vaccines, and the dose-response association of humoral responses with vaccine effectiveness.

Women with schizophrenia have threefold risk of interpersonal violence during and after pregnancy

Pregnant and postpartum people with schizophrenia have a more than threefold increase in the risk of an emergency department visit for interpersonal violence, compared with those without schizophrenia, according to a new study in CMAJ.

Researchers optically evoke tachycardia enhanced anxiety-like behaviour

In a recent study published in the journal Nature, researchers devised a non-invasive optogenetic and wearable cardiac pacemaker for accurate and specific control of cardiac rhythm for ≤900 beats per minute (bpm), enabled by micro-light-emitting display (LED) harness and systemic channelrhodopsin delivery.

Even small bouts of exercise protective against heart disease, cancer

In a recent article published in the British Journal of Sports Medicine, researchers explored the relationship between non-occupational physical activity (PA) levels and poor cardiovascular diseases (CVDs) and cancer outcomes, including mortality.

Review highlights the effectiveness of diet-based low-density lipoprotein lowering over medication

In a recent article published in the journal Nutrition, researchers in Australia summarized how diet could help decrease low-density lipoprotein cholesterol (LDLc) or triglyceride concentrations in polygenic hypercholesterolemia.

Messages about the cardiovascular benefits of flu vaccination boost vaccine uptake

Making a connection between the flu and the risk of subsequent heart problems significantly increased flu vaccination rates among older Danish adults, according to a study presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology. A reminder message the day before the start of a national vaccine program also helped "nudge" people to get vaccinated.

Study investigates how people use emojis to express or mask emotions

Scientists asked 1,289 people who use emojis to respond to internet chat messages and report their feelings and emoji use. They found that more emojis were used between closer friends, that using positive emojis to express positive feelings correlated with personal wellbeing, and that positive emojis could be used to mask the expression of negative feelings.

Eliminating medication copays does not reduce cardiovascular-related chronic conditions

Providing medications for chronic diseases—for example, cholesterol-lowering, blood pressure and diabetes medications—free of charge for three years did not have a significant impact on serious health outcomes associated with those conditions among low-income seniors in Canada, according to a study being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Assistance dogs help improve defense veterans’ mental health, study shows

A new Australian study focused on defence veterans’ mental health has found strong evidence that assistance dogs used in conjunction with traditional therapies provide the most effective treatment outcomes.

Using intravascular imaging to visualize narrowed coronary arteries improves outcomes after stenting

Patients with complex coronary artery disease who underwent a stenting procedure guided by intravascular imaging were nearly 40% less likely to die of heart disease, have a heart attack caused by a new blockage in the treated artery or need a repeat stenting procedure in the treated artery, compared with similar patients who underwent a standard angiography-guided stenting procedure, according to research presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Immediate complete revascularization is not inferior to staged procedure for treating multi-vessel disease

In patients with multi-vessel heart disease who have had a heart attack, immediate treatment with stents in all diseased arteries was found to be as safe and effective at one year of follow-up as staged treatment, according to findings from the first large, randomized trial to address this question that is being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology. In staged treatment, the blocked artery that caused the heart attack is treated with a stent immediately and other partially blocked arteries are treated in a second procedure up to six weeks later.

Minimally invasive mitral valve repair is as safe and effective as conventional surgery, trial shows

In the largest randomized trial conducted to compare minimally invasive and conventional cardiac surgical techniques for repairing a poorly functioning mitral valve, improvements in physical activity, as well as surgical outcomes and quality of life, were similar in both groups of patients at 12 weeks post-surgery.

Transcatheter-based mitral valve repair safe and effective for nearly 9 out of 10 patients

The largest study to examine outcomes for patients treated outside a clinical trial setting with a minimally invasive procedure to repair a poorly functioning mitral valve in the heart found that the procedure was safe and resulted in a successful repair for nearly 9 out of 10 patients, researchers reported at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology. Patients whose procedure was successful were half as likely to die within one year compared with those in whom the procedure was unsuccessful.
