Essential Heterogeneity

Acute myocardial infarction (AMI) is one of the main causes of morbidity and mortality, both in the Russian Federation and around the world. Approximately, in up to 10% of patients with clinical diagnostic features of AMI, early angiography does not reveal an occluded vessel or possibly any evidence of coronary artery disease. These patients constitute an intriguing subgroup referred to as “Myocardial Infarction with Non-Obstructive Coronary Arteries” (MINOCA). MINOCA is a collective concept that unites many different pathologies, which determines the essential heterogeneity of the etiological factors. Coronary artery embolism is recognized as an important non-atherosclerotic cause of AMI. In turn, the most common underlying disease in those with coronary embolism is the atrial fibrillation. The advantages of reperfusion strategy and cardioprotective therapy in the treatment of obstructive arteriosclerosis are well studied, widely presented in the literature and supported by a strong evidence base, while the issues of diagnosis and treatment of patients with MINOCA are currently widely discussed We present two clinical cases of embolic myocardial infarction in patients with atrial fibrillation, diagnosed in our clinic in 2017.

Paradoxical coronary artery embolism is often an underdiagnosed cause of acute myocardial infarction (MI). It should always be considered in patient with acute MI and a low risk profile for atherosclerotic coronary artery disease. We describe a patient with simultaneous acute saddle pulmonary embolism (PE) and acute ST segment elevation MI due to paradoxical coronary artery embolism. Transoesophageal echocardiography demonstrated a patent foramen ovale with right to left shunt and large saddle PE in the main pulmonary artery and coronary angiography demonstrated acute thrombotic occlusion of the right coronary artery.

Coronary Embolism

Previous cases of coronary embolism as a cause of myocardial infarction (MI) in association with prosthetic mechanical valves have been reported, but the fact that the patient was not aware of the importance of maintaining anticoagulation therapy is relevant in this case. A 16-year-old female was referred for primary coronary intervention due to subacute anterolateral ST elevation MI, after she decided to discontinue warfarin therapy three weeks before. Coronary angiography showed distal occlusion of the left anterior descending coronary artery with an image suggesting embolic material. Conventional echocardiography demonstrated akinesia of anteroseptal, inferior, and posterior segments of the left ventricle, with severe systolic dysfunction, beyond the intraventricular thrombus. The presence of mechanic aortic prosthesis and no anticoagulation therapy are highly suggestive of coronary embolism as the cause of MI. This case report confirms that patient education is vital in our struggle to prevent this complication in high-risk patients.
