People who survive ischemic stroke are more likely to have major heart problems in the first month after a stroke, and, as a result, have a higher risk of death, stroke or any other stroke within five years, compared to people. which do not develop heart problems early after stroke, according to a new study published today in pulse.

Ischemic pulse is the most common type of stroke — which accounts for 87% of all strokes — and occurs when blood flow to the brain is blocked. After a stroke, people often have complications of the heart and blood vessels, known as stroke. Heart problems include severe heart attack, angina (chest pain), heart problems such as atrial fibrillation, arrhythmia and ventricular fibrillation; heart attack; heart failure or Takotsubo (broken heart disease), a type of stress that results in the temporary expansion of a part of the heart that affects its ability to pump properly. These conditions increase the risk of disability or death in the short term, however the long-term effects for people with heart disease are unknown.

“We know heart disease and stroke share the same risk factors, and there are two possible links between stroke risk and heart disease. For example, heart conditions such as fibrillation increase the risk of stroke, and stroke also increases the risk of heart attack, ”said Benjamin JR Buckley, Ph.D., lead author of the study and a postdoctoral fellow in prevention of heart disease. Liverpool Center for Cardiology, Liverpool University in the UK. heart problems they are post-traumatic stress disorder and, importantly, whether stroke is associated with an increased risk of major long-term events. “

The researchers analyzed the medical records of more than 365,000 adults who were treated for stroke at more than 50 clinics in the United States, between 2002 and 2021. The people diagnosed had a heart attack within four weeks after the stroke. blood suits them. the exact number of stroke survivors who did not experience these heart problems within four weeks (and care team).

After adjusting for confusing factors, such as age, sex and ethnicity / ethnicity, and comparing stroke survivors with new heart problems to those who did not, the study found:

  • Overall, of all the survivors of stroke in the study, almost 1 in 10 (11.1%) experienced acute myocardial infarction, 8.8% were diagnosed with atrial fibrillation, 6.4% developed with heart failure, 1.2% exhibited severe ventricular arrhythmias and 0.1% developed ‘fractured heart. ‘pain within four weeks after stroke.
  • The risk of death within five years after stroke increased significantly among participants with new heart problems: 49% more likely if they persisted. acute heart attack; 45% more likely to develop fibrillation / flutter; and 83% more likely if they continue heart attack. Severe arrhythmias double the risk of death.
  • Clinical resuscitation and heart rate within five years after stroke are also higher among those who experience a heart attack within a one-month period.
  • Survivors of stroke with Takotsubo were 89% more likely to have a major heart attack within five years after stroke.
  • The people who developed atrial fibrillation after stroke they were 10% more likely to have a second stroke in the five years after stroke.
  • People suffering from high blood pressure and new infections complications of the heart and blood vessels they were 50 percent more likely to develop a stroke within five years after the first stroke.

“I was amazed at how common the stroke was and how high the heart rate was in all of the adult stroke groups,” Buckley said. “This means that this is a very dangerous community where we need to focus on secondary prevention efforts.”

The results of the study build on an understanding of the dual pathway between the brain and the heart and expand this understanding to long-term health outcomes. “We are working on further research to determine how heart attack may be more predictable,” Buckley said.

“We also need to improve and implement treatments to improve outcomes for people with stroke,” Buckley said. “For example, exercise-modified exercise may be helpful after a stroke, so for people suffering from stroke and new heart problems, it should also be helpful, perhaps even more so. I think this is an interesting area for future research. “

Limited readings include that it is a background research and knowing whether heart problems identified after another ischemic stroke Stroke is caused by or contributed to stroke, it is not known.

“This study highlights why it is important for psychiatrists and psychologists to work hand in hand with patients and each other to understand why early stroke occurs and to make a full assessment to identify new risk factors. for a stroke and cardiovascular disease may need to start with preventive measures, ”said Lee H. Schwamm, MD, chair of the Volunteer Committee of the National Institutes of Health. Technological experts experienced professional skilled skilled skilled skillful specialists of a specialist specialist specialists of Massachusetts in Boston. “The American Academy of Pediatrics recommends a secondary star prevention system for any stroke.”
