Significant Increase Seen in US Emergency Room Visits for Irregular Heartbeat

Latest research indicates that emergency room visits for atrial fibrillation have increased significantly in the United States. This research was presented at the American Heart Association's Scientific Sessions 2014.

Atrial fibrillation (AF), the most common kind of arrhythmia or irregular heartbeat, can lead to blood clots, stroke, heart failure and other heart-related complications.

Stroke – Early Warning Signs - Risk Factor - Rehab - Treatment
Stroke can cause permanent disability and it is important to recognize its early warning signs to stop its progress. Early warning signs of stroke include sudden weakness of facial muscles.

Researchers analyzed patients from the Nationwide Emergency Department Data who visited the emergency department with AF listed as the first diagnosis in 2006-11. They found:

The average AF hospital admission rate was 65 percent.
The admission rate for AF varied from 62.5 percent in 2006 to 67 percent in 2011.
The rate of AF emergency room visits steadily increased 24 percent, from 133 visits per 100,000 persons in 2006 to 165 visits per 100,000 persons in 2011.

How to Deal with a Stroke - Signs - Symptoms - Risk Factors - Prevention
Stroke is a brain attack, which occurs when the blood supply to the brain is interrupted. It affects all age groups; according to the WHO, 15 million people are affected by stroke annually.
The total admissions for AF (2006-11) was more than 2.7 million.
While AF admission rates have risen, there was a decrease in in-hospital death rates (1.18 percent in 2006 to 0.97 percent in 2011) which points to improving care of hospitalized patients.

Drug intervention need not be the only option to help lower your moderately high blood pressure. Lifestyle changes along with herb remedies such as garlic, arjuna, sarpagandha, and olive can serve the purpose.

Patient characteristics associated with higher admissions rates include those who were elderly, female, had Medicare or Medicaid insurance, lived in areas with low median income, or visited teaching hospitals and those in the northeast and metropolitan areas.

"The huge demographic and geographic variations highlight the unmet need for interventions to decrease hospitalization rates," said Sourabh Aggarwal, M.D., study lead researcher.
