Of course, sudden cardiac death is now a very common cause of death. At places like airports and bus stations, we often see reports of such incidents, and many young people are also affected. However, patients experiencing sudden cardiac death generally do not present with symptoms of vomiting blood, as it is caused by cardiac arrest. Vomiting blood is usually associated with conditions such as gastric ulcers leading to severe bleeding, gastric cancer, or cirrhosis leading to rupture of varicose veins at the base of the stomach. The likelihood of vomiting blood occurring in cases of sudden cardiac death is very low, almost nonexistent.
