Ischemic heart disease in absence of obstructive coronary artery disease. Should we be surprised? Insights from INOCA (Ischemia with Non-Obstructive Coronary Arteries) and MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries)Cardiopatia ischemica senza aterosclerosi coronarica ostruttiva. Ci dobbiamo stupire? Riflessioni su INOCA (Ischemia with Non-Obstructive Coronary Arteries) e MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) Enrico Orsini, MD ARCA Toscana, Pisa Abstract Le sindromi miocardiche ischemiche rappresentano un gruppo di patologie cardiache sostenute da cause molteplici e con una espressione clinica estremamente variabile, che condividono un unico elemento comune: l'ischemia miocardica. Parole chiave: INOCA; MINOCA; Sindromi miocardiche ischemiche; Ischemia miocardica. Abstract Myocardial ischemic syndromes represent a group of cardiac diseases sustained by multiple causes and with a widely variable clinical expression, which share one common element: myocardial ischemia. Atherosclerotic obstruction of coronary arteries, although an important cause of ischemia, is not sufficient to globally explain the ischemic syndrome, both in chronic and acute forms. Many functional mechanisms of macrovascular, microvascular, and nonvascular nature contribute in varying extent to the pathogenesis of the syndrome. Among patients with chronic myocardial ischemic syndromes, INOCA (Ischemia with Non-Obstructive Coronary Arteries) accounts for 33% in males and 65% in females. MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) accounts for 5-15% of all forms of acute myocardial infarction. Patients with INOCA and MINOCA pose a diagnostic and therapeutic challenge to the cardiologist as they are often undiagnosed and undertreated. Diagnostic investigations to ascertain individual ischemic mechanisms are essential to institute a tailored treatment. The overlap between obstructive coronary artery disease with the underlying mechanisms of INOCA/MINOCA can lead to unnecessary treatment of functionally nonischemic coronary artery stenoses, contributing to the persistence/recurrence of symptoms and poor quality of life of these patients. Key words: INOCA; MINOCA; Myocardial ischemic syndromes; Myocardial ischemia. |
