[Acute myocardial infarction and bronchoalveolar carcinoma. Association or coincidence?].
The aim of this paper is to report for the first time the association between bronchiolo-alveolar carcinoma and acute myocardial infarction (AMI). Two patients suffering from this association were studied. A 59 year old male, diabetic, alcoholic and smoker was admitted because a diaphragmatic AMI. An interventricular septal defect and papillary posterior muscle rupture were confirmed at autopsy. A 0.8 cm diameter friable mass was found in the right lung superior lobe. The second case was a 69 year old male, smoker, who presented with a diaphragmatic and right ventricular posterior wall AMI. A round 1 cm diameter tumor was observed at the right lung superior lobe. It had a caseous aspect lying over a fibrous scar. Both cases had severe right coronary artery narrowings with recent occlusive thrombi. The cardiac valves were free of non-bacterial thrombotic endocarditis. Therefore the possibility of coronary embolization was discarded. As lung carcinomas produce vasospastic and thrombogenic mucins, these substances could have been responsible for the acute coronary thrombosis.
