Women once considered low risk for heart disease show evidence of previous heart attack scars
Women who complain about chest pain often are reassured by their doctors that there is no reason to worry because their angiograms show that the women don't have blockages in the major heart arteries, a primary cause of heart attacks in men. But a National Institutes of Health study shows that about 8% of those women actually have scars on their heart that indicate they experienced a heart attack. (2018-02-20)

Association of risk of death and cigar, pipe and cigarette use
Contemporary population estimates suggest that like cigarette-only smokers, current cigar-only and pipe-only smokers have a higher risk of dying from cancers known to be caused by tobacco, and cigarette and cigar smokers have a higher risk of death from any cause compared with people who never used tobacco. (2018-02-19)

Just a few minutes of light intensity exercise linked to lower death risk in older men
Clocking up just a few minutes at a time of any level of physical activity, including of light intensity, is linked to a lower risk of death in older men, suggests research published online in the British Journal of Sports Medicine. (2018-02-19)

Shorter time between first medical contact to PCI in heart patients linked to saving lives
Heart experts are calling for immediate action following new research in the European Heart Journal that shows every minute counts for patients who suffer the most severe type of heart attack. The study shows numbers of deaths rise steadily and rapidly the longer the time between patients' first contact with a medical professional and when they are treated in hospital with percutaneous coronary intervention (PCI) to insert a balloon catheter to widen blocked arteries and restore blood flow to the heart. (2018-02-13)

Acute coronary syndromes -- Did prasugrel & ticagrelor offer same benefits as clopidogrel?
In patients presenting with acute coronary syndromes (ACS) either with or without ST-segment elevation MI (STEMI and NSTEMI), dual antiplatelet therapy (DAPT) is recommended for at least 1 year independently of whether revascularization is performed. (2018-02-07)

Case for assisted dying 'stronger than ever' says The BMJ
A series of articles published by The BMJ today, explore the debate around assisted dying, in which, subject to safeguards, terminally ill people who are near to death, suffering, and of sound mind, could ask for drugs that they would take to end their lives. (2018-02-07)

Restoring levels of coenzyme Q10 (CoQ), a key molecule in energy production in cells, could overcome insulin resistance or pre-diabetes -- a precursor to type 2 diabetes and cardiovascular disease. (2018-02-06)

Inadequate follow-up for many cardiac arrest patients
A major international study shows that if cardiac arrest patients are treated like heart attack patients only, this will potentially have negative consequences on their rehabilitation and return to working life. These patients often lack follow-up of the injuries they may have suffered to the brain in connection with their cardiac arrest, the researchers found. (2018-02-05)

Patients with kidney disease with heart defibrillators at greater risk of hospitalization
In a study of nearly 6,000 community-based patients with chronic kidney disease and heart failure, the use of implantable cardioverter defibrillators was associated with a significantly increased risk of subsequent hospitalization. (2018-02-05)

Four in 10 cardiomyopathies -- a major cause of sudden death in young people -- are genetic
Four in 10 cardiomyopathies -- a major cause of sudden cardiac death and heart failure in young people -- are genetic, according to a European Society of Cardiology (ESC) study published today in European Heart Journal. Family screening is urgently needed to prevent early death in apparently healthy relatives, the paper says. (2018-01-24)

Lifesaving microbubbles
Severe oxygen deficiency eventually leads to cardiac arrest. If the blood's oxygen content cannot be rapidly re-established, the patient may die within minutes. In the journal Angewandte Chemie, American scientists have introduced air-filled microbubbles that could be used as an intravenous oxygen carrier to increase the survival rate of such patients. Because they rapidly dissolve in blood, the risk of embolism is minimal. (2018-01-23)

Overall in-hospital cardiac arrest survival improves, lower survival on nights, weekends
Overall survival has improved for the approximately 200,000 patients experiencing in-hospital cardiac arrest in the US each year, but patients who arrest during nights or weekends continue to experience lower survival compared to patients who arrest during daytime hours. Survival to discharge in patients who arrested during 'off-hours' was an absolute 3.8 percent lower compared to patients who arrested during 'on-hours,' according to a study published today in the Journal of the American College of Cardiology. (2018-01-22)

'Heart-on-a-chip' process aims to speed up drug testing
Testing new clinical drugs' effect on heart tissue could become quicker and more straightforward, thanks to new research from Harvard University. The study, published today in the journal Biofabrication, sets out a new, faster method for manufacturing a 'heart-on-a-chip,' which can be used to test the reaction of heart tissue to external stimuli. (2018-01-16)

'Decorating' cardiac stem cells with platelet nanovesicles can increase the stem cells' ability to find and remain at the site of heart attack injury and enhance their effectiveness in treatment. (2018-01-10)

Heart-muscle patches made with human cells improve heart attack recovery
Large, human cardiac-muscle patches created in the lab have been tested, for the first time, on large animals in a heart attack model. This clinically relevant approach showed that the patches significantly improved recovery from heart attack injury. The results are a step closer to the goal of treating human heart attacks by suturing cardiac-muscle patches over an area of dead heart muscle in order to reduce the pathology that often leads to heart failure. (2018-01-10)

Middle-aged couch potatoes may reverse heart effects of a sedentary life with exercise training
Two years of exercise training during middle age may reduce or reverse the cardiac consequences of a sedentary lifestyle. Two years of exercise training may be an effective lifestyle modification for rejuvenating aging hearts and reducing the risk of heart failure. (2018-01-08)

Activity monitors only effective when users set goals

Scientists uncover why sauna bathing is good for your health
Scientists at the University of Eastern Finland have shown that sauna bathing is associated with a variety of health benefits. Using an experimental setting this time, the research group now investigated the physiological mechanisms through which the heat exposure of sauna may influence a person's health. Their latest study with 100 test subjects shows that taking a sauna bath of 30 minutes reduces blood pressure and increases vascular compliance, while also increasing heart rate similarly to medium-intensity exercise. (2018-01-05)

Excess fat disrupts heart cell's energy system
A University of Iowa study finds that lipid overload in heart cells, a common feature in diabetes and obesity, leads to misshapen mitochondria that don't produce energy efficiently. This structural disruption may contribute to the two- to five-fold increased risk of heart failure in people with diabetes. (2018-01-05)

Trastuzumab: No negative impact on cardiac function
Long-term follow-up results of the NRG Oncology trial NSABP B-31 have shown that the addition of trastuzumab to adjuvant chemotherapy does not negatively affect cardiac function in women with node-positive, human epidermal growth factor receptor 2 (HER2)-positive, early-stage breast cancer who survive without cancer recurrence. (2018-01-03)

Researchers at Lund University in Sweden have found that the presence of death receptors in the blood can be used to directly measure the risk of developing cardiovascular diseases and type 2 diabetes. 'We see that people with known risk factors such as high blood sugar and high blood fats also have heightened death receptor levels', says Professor Jan Nilsson who led the study. (2017-12-11)

Abnormal electrocardiogram findings are common in NBA players
About 1 in 5 professional basketball players had abnormalities on their electrocardiograms (ECGs), some but not all of which were explained by changes in the shape and size of their hearts as a result of athletic training. (2017-12-06)
