GPs undertreat women with atrial fibrillation
- ScienceDaily
- 13/8/31 17:09
Women with atrial fibrillation are undertreated compared with men regardless of their stroke risk and comorbidities. This study has revealed a significant gap between guidelines and practice and requires GPs and cardiologists to work together to optimize treatment for women.
High dose statins prevents dementia, study suggests
- ScienceDaily
- 13/8/31 17:09
High doses of statins prevent dementia in older people, according to new research. The study of nearly 58,000 patients found that high potency statins had the strongest protective effects against dementia.
Impact of AF on stroke risk eliminated with multiple risk factors
- ScienceDaily
- 13/8/31 17:09
Patients with five or more risk factors have the same stroke risk as patients with atrial fibrillation, according to new research. The study included data on more than 4 million patients from Danish registries over a 10 year period.
Mass screening identifies untreated AF in 5% of 75-76 year olds
- ScienceDaily
- 13/8/31 17:09
Mass screening in more than 25,000 Swedish residents has identified untreated atrial fibrillation in 5 percent of 75-76 year olds, putting them at increased stroke risk.
Reimbursement systems influence achievement of cholesterol targets
- ScienceDaily
- 13/8/31 17:09
The type of healthcare reimbursement system influences the achievement of cholesterol targets, reveals new research. The analysis found that fewer patients reached the target in countries with restrictive (e.g. Germany) compared to incentive (e.g. the UK) systems.
Short-term smoking cessation reverses endothelial damage
- ScienceDaily
- 13/8/31 17:09
Eight weeks of smoking cessation reverses the endothelial damage caused by smoking, according to new research. Serotonin remained elevated, suggesting eight weeks of cessation is insufficient to reverse the risk of myocardial infarction.

Smokers who survive to 70 still lose an average of four years of life, according to new findings.
Statins prevent cataracts, study suggests
- ScienceDaily
- 13/8/31 17:09
Statins lower the rate of cataract by 20 percent, according to new research. The risk of cataract was reduced by 50 percent when treatment was initiated in younger individuals (in their 40s) and the duration of therapy was longer (e.g. up to 14 years).
Statins reduce cardiovascular events in coronary artery disease patients with very low LDL cholesterol levels
- ScienceDaily
- 13/8/31 17:09
Aggressive treatment with statins reduces the risk of subsequent cardiovascular events in patients with coronary artery disease even if they have very low LDL cholesterol levels, reveals new research.
STEMI incidence falls in southern Switzerland after smoking ban implemented
- ScienceDaily
- 13/8/31 17:09
STEMI incidence fell in southern Switzerland after implementation of the smoking ban in public places, reveals new research. 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...
