ANSWER: Heart attack
 
Do you know? - Our genes store heart attack memoryMemory of a heart attack gets stored in the genes through epigenetic changes, chemical modifications of DNA that turn genes off or on according to a study.
  • CVDs or cardiovascular diseases are the leading cause of death worldwide- these are influenced by environmental and hereditary factors
  • CVD includes diseases of heart and circulation including CHD, angina, heart attack, congenital heart disease and stroke
  • Study examined epigenetic changes leading to the development of numerous diseases, in people who have had a previous heart attack
  • During the heart attack, the signals of the body are activating certain genes- mechanism protects the tissue during the acute stages of the disease and restores the body after the heart attack- epigenetic changes are also associated with a heart attack- according to Asa Johansson, researcher at Sweden’s Uppsala University
  • Results of the study show many epigenetic changes in individuals who experienced a heart attack
  • This points to the possibility of understanding heart attacks in a complete clinical picture and revolutionising treatment.
