Tool to predict the 30-day risk of death or mortality for acute heart failure patients

Currently, physicians in the emergency department of a hospital cannot reliably classify patients suffering from acute heart failure symptoms according to their death risk. Now, a simple, highly reliable and accurate tool to predict a 30-day risk of death for acute heart failure patients, who are under treatment in the emergency medical department has been developed by researchers from the Spanish Ministry of Health.

Researchers tested the 30-day risk of death prediction tool in 4,867 heart patients in Spain between 2009 and 2011. They further corroborated the functioning of the tool by predicting a 30-day risk of death in 3,229 heart patients for about three years. The tool in its risk of death prediction uses factors such as

  • Age of the patient.
  • Heart's 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 admission in the hospital.

Lead authors of the study were Oscar Miro, Hospital Clinic, Barcelona, Spain. The study findings were published 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 Barthel 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 stroke patient's dependence in performing daily routine activities. This index scores patient's ability in performing ten routine functions such as bathing, using steps, dressing, moving from bed to chair, walking, eating, toilet usage, grooming etc.


Heart attack or stroke risk with an exciting sport event

A study done by researchers shows watching a live sport on TV or at a stadium causes intense emotional stress and marked elevated heart rates. The elevated heartbeat rates may trigger a cardiovascular event in a heart attack or stroke risk patients.

Researchers have found elevated heartbeat rates during exciting moments of the game. Heartbeat rate (measured with a Holter monitor) of the fans were increased by 75 percent while watching in a live TV and by 110 percent while watching in a stadium. These heartbeat rates are equal to cardiac stress caused by a vigorous exercise program. They observed that heartbeat rates increase on an average of 92 percent.

Authors are advising GPs to warn high heart attack or stroke risk patients not to watch live hockey sport in a TV or at a stadium as "excitement with victory" or "pain with defeat" may cause a negative effect on the cardiovascular system and subsequently trigger a heart attack or stroke event.

Senior investigator of the study was Professor Paul Khairy, MD, PhD, Montreal Heart Institute, affiliated to Montreal University, Montreal, Quebec, Canada. The study findings were published October 5, 2017, in the Canadian Journal of Cardiology. Title of the article was "Heart Rate Response in Spectators of the Montreal Canadians Hockey Team."
