A Chinese man got so angry while tutoring and helping his teenage son with his homework that he suffered a heart attack and almost lost his life

Surnamed Zhang, the 40-something man from China’s Zhejiang province started experiencing shortness of breath and chest pain while helping his son prepare for senior secondary school entrance exams. Things got so tense between the two that Zhang was rushed to the hospital, where he was diagnosed with acute myocardial infarction. Doctors at the Sir Run Run Shaw Hospital performed emergency artery bypass surgery and managed to save Zhang’s life. The cause of the heart attack was attributed to premature coronary artery disease, a life-threatening condition often exacerbated by stress.
