I had taken the sildenafil 100 mg tablet on 14th November for the first time in my life. After 10 days on 24th November I experienced chest pain and had to do Angiography which revealed the thrombosis in LAD. Considering my age 39 years doctors decided to avoid Angioplasty and two injections of Antiplatelet and anti coagulation was given to dissolve the thrombosis. Now I am feeling better and no more chest pain. Medicines being taken 1. brilinta 90 mg, 2. Met XL 12.5, 3. Ecosprin 75, 4.Rosave 20 mg, 5.Homochek. My question: Is the Sildenafil 100 mg medicine responsible for the thrombosis in LAD. I was a healthy person with no complain of chest pain or any other symptoms of heart disease then how and when this blood clot was developed in left coronary artery.
