A recent U.S. study found that smoking increases a common arrhythmia – atrial fibrillation risk, this is the first link found in smoking and atrial fibrillation.
The study involved 15,000 adults aged 45 to 64. The researchers conducted a survey on the average being 13 years of follow-up survey, during which the survey was a total of 876 people suffering from atrial fibrillation.
The researchers compared the risk of smokers and non smokers chances of atrial fibrillation. The results showed that, compared with never smokers, had quit smoking but then the person suffering from atrial fibrillation risk 1.32 times higher, current smokers will have more than 2 times.
Atrial fibrillation, is the loss of regular cardiac contractile activity, rather than replace them with the coordination of rapid vibration, resulting in atrial contraction can not be properly effective. It can cause serious complications such as heart failure and arterial embolism, a serious threat to health.
According to statistics, the United States each year with newly diagnosed cases of atrial fibrillation of 16 million. Previous studies have found that obesity, hypertension and diabetes are risk factors that lead to atrial fibrillation. This latest study confirmed that atrial fibrillation is also associated with smoking.

Cigarette smoking increases the risk of coronary heart disease, but whether smoking increases atrial fibrillation (AF) is uncertain.
The purpose of this study was to determine the association of cigarette smoking with incident AF in a population-based cohort of blacks and whites.
We determined the risk of incident AF through December 2002 in relation to baseline (1987–1989) smoking status and cigarette-years of smoking in over 15,000 participants of the prospective Atherosclerosis Risk in Communities (ARIC) study.
Over a mean follow-up of 13.1 years, 876 incident AF events were identified. Compared to never smokers, the multivariable-adjusted hazard ratios (HRs) for AF were 1.32 (95% confidence interval [CI] 1.10–1.57) in former smokers, 2.05 (95% CI 1.71–2.47) in current smokers, and 1.58 (95% CI 1.35–1.85) in ever smokers. In the highest tertile of accumulated smoking amount (>675 cigarette-years), the incidence of AF was 2.10 times greater (95% CI 1.74–2.53) than in those who never smoked. Associations were similar by gender, race, type of event (AF and atrial flutter), and when only AF events identified by study exam ECGs were included. Finally, individuals who quit smoking exhibited a trend indicating a slightly lower risk of developing AF (HR 0.88, 95% CI 0.65–1.17) compared to those who continued to smoke.
Smoking was associated with the incidence of AF, with more than a two-fold increased risk of AF attributed to current smoking. In addition, a trend toward a lower incidence of AF appeared among smokers who quit compared to continued smokers.

Approximately five to ten percent of patients with primary or metastatic cancer suffer from devastating neurological complications such as headaches, seizures, confusion, difficulty swallowing and visual disturbances. These deficits are caused by a life-threatening form of brain invasion from cancer called neoplastic meningitis. Santosh Kesari, MD, PhD, at the University of California, San Diego School of Medicine and colleagues have utilized a novel combined technique to treat cancer patients by bathing the brain in chemotherapy and relieving pressure from spinal fluid build-up (hydrocephalus). The results of this multicenter study are described in Journal of Neurosurgery, now available online. www.physorg.com
