Researchers discover how heart arrhythmia occurs – Researchers have discovered the fundamental biology of calcium waves in relation to heart arrhythmias. The findings published this month in the January 19 edition of Nature Medicine outlines the discovery of this fundamental physiological process that researchers hope will one day help design molecularly tailored medications that correct the pathophysiology.
Findings Not Supportive of Women-Specific Chest Pain Symptoms in Heart Attack Diagnosis – Using chest pain characteristics (CPCs) specific to women in the early diagnosis of acute myocardial infarction (AMI, heart attack) in the emergency department does not seem to be supported by the findings of a study published by JAMA.
High salt levels in common medicines put patients at increased risk of cardiovascular events — Researchers call for salt content of medicines to be labeled in same way as foods – Taking the maximum daily dose of some medicines would exceed the recommended daily limits for sodium, without any additional dietary intake. Public should be warned about the potential dangers of high sodium intake from prescribed medicines, reveals new study.
STEMI incidence falls in southern Switzerland after smoking ban implemented – Second-hand smoke increases the risk of coronary artery disease and acute myocardial infarction. For this reason, health policies aimed at reducing tobacco consumption and public smoke exposure are strongly recommended.
Air pollution and hardening of arteries — Long term exposure to air pollution may be linked to heart attacks and strokes by speeding up atherosclerosis – Long term exposure to air pollution may be linked to heart attacks and strokes by speeding up atherosclerosis, or “hardening of the arteries”. The researchers found that higher concentrations of fine particulate air pollution (PM2.5) were linked to a faster thickening of the inner two layers of the common carotid artery, an important blood vessel that provides blood to the head, neck, and brain.
Strawberries, blueberries may cut heart attack risk in women — American Heart Association Rapid Access Journal Report – Eating three or more servings of blueberries and strawberries per week may help women reduce their risk of a heart attack by as much as one-third. Blueberries and strawberries contain high levels of naturally occurring compounds called dietary flavonoids, also found in grapes and wine, blackberries, eggplant, and other fruits and vegetables.
First Polypill trial in people selected on age alone (50 and over) shows substantial health benefit – Results of a randomised trial carried out by academics at Queen Mary, University of London show that a four-component Polypill given to people aged 50 and over to reduce their risk of heart attack and stroke, the most common causes of death worldwide, achieved large reductions in blood cholesterol and blood pressure, the main causes of these two diseases.
Study Links ‘Body Clock’ to Sudden Cardiac Death — ‘Biological clock’ may be behind sudden heart attacks – A new study uncovers the first molecular evidence linking the body’s natural circadian rhythms to sudden cardiac death (SCD). Ventricular arrhythmias, or abnormal heart rhythms, are the most common cause of sudden cardiac death: the primary cause of death from heart disease. They occur most frequently in the morning waking hours, followed by a smaller peak in the evening hours.
Short-Term Exposure to Most Major Air Pollutants Associated With Increased Risk of Heart Attack – Short-term exposure (for up to 7 days) to all major air pollutants, with the exception of ozone, is significantly associated with an increased risk of heart attack. The potentially harmful effect of episodes of high air pollution on health has been suspected for more than 50 years.
