Five Early Warning Signs of a Heart Attack

Highlights Early Warnings Symptoms of a Heart Attack Dr. O’Keefe-McCarthy cited a number of previous studies that have suggested women tend to experience more warning symptoms compared with men. Women tend to experience less prodromal chest pain, but reported more episodes of fatigue, anxiety, and head-related symptoms such as headache or dizziness compared with their male counterparts. Dr. McSweeney and her colleagues identified the five specific prodromal symptoms that appear to be most predictive of future cardiac events: –Unusual fatigue –Discomfort in… Keep Reading

Most Diagnostic Tests Miss Heart Attacks

  63% of the myocardial infarctions identified by cardiosvacular medical imaging were missed in routine medical care,  Highlights Most Heart Attacks Are Missed in Routine Medical Care Unrecognised heart attacks  refer to sub-clinical events that are missed in routine medical care but are picked up by electrocardiogram (ECG) or by cardiovascular magnetic resonance (CMR) imaging, which is more accurate.  63% (156 out of 247) of the myocardial infarctions identified by CMR were missed in routine medical care,” said Dr Acharya.… Keep Reading

Effects of Weather on Heart Failure

 Lag effects of temperature and other meteorological parameters on heart failure events were limited but present.  -Highlights- Dropping temperatures and changes in atmospheric pressure can lead to an increase in the risk of heart failure for elderly people. We measured the lag effects of temperature, relative humidity, atmospheric pressure and fine particulate matter (PM2.5) on hospitalizations and deaths for heart failure in elderly diagnosed with this disease on a 10-year period in the province of Quebec, Canada. We observed an… Keep Reading

Atrial Fibrillation, Stroke and Colder Temperatures

Compared to summer, the risk of ischaemic stroke increased by 10% in spring and 19% in winter. Highlights Cold Weather and Stroke Risk from Atrial Fibrillation Until now it was unclear whether the risk of ischaemic stroke was higher in AF patients during cool seasons or on days with a lower temperature; The study investigated this issue in 28 ,559 new-onset AF patients from the “National Health Insurance Research Database” inTaiwan during 2000 to 2011. The risk of ischaemic stroke was… Keep Reading

How Does High Altitude Affect People with Heart Problems?

Highlights High Altitude Exposure Among People With Cardiovascular Conditions   Physiological acclimatization to altitude can impose an increased workload on the cardiovascular system. At high altitudes, considered those higher than 2500 m (~8200 ft) above sea level, physiologic responses may start to represent challenges for the human body. High altitude is associated with progressive reduction in barometric pressure, air temperature, and humidity. A reduction in barometric pressure results in “hypobaric hypoxia.” High altitude is associated with increases in systemic blood… Keep Reading
