A Tool To Predict The 30-Day Risk Of Death (Mortality) In Patients From An Acute Heart Failure
Currently, physicians in the emergency department of a hospital cannot reliably classify the patients suffering from acute heart failure symptoms according to their risk of death. Now, a simple, highly reliable and accurate prediction tool to predict a 30-day risk of death in an emergency medical patient from an acute heart failure has been developed by the researchers from the Spanish Ministry of Health.
The researchers have tested the prediction of 30-day risk of death on 4,867 heart patients in Spain between 2009 and 2011. They further corroborated the functioning of the tool on 3,229 heart patients for about three years by predicting a 30-day risk of death. The tool uses the following factors in the prediction of 30-day risk of death.
- Age of the patient.
- The systolic blood pressure.
- Respiratory rate. Normal breathing at rest is 12 breaths per minute.
- Potassium levels in the bloodstream. Normal levels are required for the functioning of nerve and muscle cells including heart muscle cells.
- The Barthel index score at the time of hospital admission.
The lead author of the study was Oscar Miro, Hospital Clinic, Barcelona, Spain. The study was published on October 2, 2017, in the journal Annals of Internal Medicine. Title of the article was "Predicting 30-day Mortality for Patients With Acute Heart Failure in the Emergency Department: A Cohort Study."
Heart failure: See congestive heart failure.
Barthel index score: The Barthel index score or Activities of Daily Living (ADL) index was introduced in the year 1965. The score ranges from 0-100 and used to measure the ability of the patient to live independently.
This score index shows the dependence of the heart patient in performing daily routine activities. This index scores the ability of the patient in performing ten routine bodily functions such as bathing, using steps, dressing, moving from bed to chair, walking, eating, using the toilet, grooming etc.
The Risk Of Heart Attack Or Stroke From An Exciting Sporting Events
A study found that watching live sports on TV or at the stadium can cause an intense emotional stress and elevated heart rates. The elevated heart rate may trigger a cardiovascular event in a patient of heart diseases.
Researchers have found an elevated heart rate during the exciting moments of the game. The heart rate (measured with a Holter monitor) of the fans were increased by 75 percent when watching live TV and by 110 percent when watching in a stadium. These heart rates are equal to a cardiac stress caused by a vigorous exercise program. They observed that the heart rate was increased on an average of 92 percent.
Authors are advising doctors to warn patients of high risk to heart attack or stroke not to watch live hockey sports on a TV or at a stadium. The "Excitement With Victory" or "Pain With Defeat" may cause a negative effect on the cardiovascular system and may cause a heart attack or stroke.
