Mr. Hassan, a 45-year-old diabetic patient, felt severe epigastric pain and repeated vomiting and sweating. He was admitted to the hospital where tests found very high blood sugar, ketones in his urine, and abnormal electrolyte and blood gas levels. The diagnosis was a myocardial infarction complicated by diabetic ketoacidosis due to stress from the heart attack. He was admitted to the intensive care unit for monitoring, treatment of his conditions, and consultation with cardiology for potential intervention due to his history of heart disease.
