About
Acute coronary syndromes have been extensively studied in recent decades, focusing mainly on myocardial infarctions with obstructive coronary artery disease and early revascularisation strategies. However, the extensive use of highly sensitive troponin tests and coronary angiography has revealed a substantial group of patients with myocardial infarction without significant coronary stenosis (≥50%). This group is referred to as myocardial infarction with non-obstructive coronary arteries (MINOCA). MINOCA are defined by evidence of a myocardial infarction with normal or near-normal coronary arteries on angiography, in the absence of an alternative diagnosis specific to the clinical presentation (e.g. sepsis, myocarditis, pulmonary embolism). MINOCA may present with different aetiologies, including coronary plaque rupture/erosion, epicardial or microvascular spasm and coronary embolism. Therefore, the diagnosis of MINOCA must be considered a 'working diagnosis', which not only requires but warrants further investigation to determine the underlying cause. In fact, the investigation of MINOCA is conducted on two levels, first by excluding disorders that mimic myocardial infarction and then by identifying the cause responsible for MINOCA. In order to identify the various underlying causes of MINOCA, a cardiac MRI and/or coronary vascular imaging approach with OCT or intravascular ultrasound (IVUS) and a coronary functional assessment of microvascular function, as well as the provocation of coronary spasms by acetylcholine testing are recommended. Moreover, the clear definition of the aetiology is of great importance considering the role they play in the most appropriate therapeutic choice.
Therefore, the creation of an Italian national database could implement not only the knowledge of this clinical condition but also its management and consequent prognosis.
Full description
Although the prevalence of MINOCA is about 5-25% of all myocardial infarctions and the prognosis is now recognised as inauspicious, with a one-year all-cause mortality rate of 3.5%, data on the specific demographics, clinical features, etiopathogenetic factors and prognosis of MINOCA patients are still currently unavailable in Italy. The aim of this study is to assess, in a real-world setting, prevalence, demographics, possible aetiological causes and diagnostic, therapeutic and prognostic data of MINOCA patients in Italy by creating a national database with ambispectively collected data. The collection of therapeutic and management data on MINOCA in an ambispective manner - retrospective and prospective patients - will make it possible to evaluate the hospital management of MINOCA and its association with patient prognosis over time. This database will serve to determine the incidence and characteristics of this pathology. In addition, it will make it possible to evaluate the nationwide management of patients with MINOCA, thus considering both the diagnostic aspects aimed at defining the aetiology, and cascade the treatments used and the patients' outcomes. As in all observational studies, the assessment of the risk/benefit ratio of patients with myocardial infarction, the administration of medical treatment and the management of the disease and treatment-related clinical events are the responsibility of the physician treating the patient. Since the purpose of the work only involves the collection of data, participation in this research will not entail any additional risk for the patient. The collection of actual data should provide valuable information on the demographics, aetiology and prognosis of MINOCA patients.
