Mechanical Complications of Acute Myocardial Infarction During COVID-19 Pandemics (CautionCov19)

June 9, 2023 updated by: Maastricht University Medical Center

Mechanical Complications of Acute Myocardial Infarction: an International Multicenter Cohort Study During COVID-19 Pandemics (CautionCov19)

The ongoing COVID-19 pandemics has put an overwhelming pressure on the healthcare systems of many European countries. Such a situation has potentially led to delayed and impaired access to appropriate treatment for patients affected by other severe, non-COVID-19-related conditions, including cardiovascular diseases. This resulted in a reported lower admission, but higher mortality rate for AMI patients.

Such a situation might be explained by many factors, including unavailability of early reperfusion therapy and late hospital presentation of AMI patients due to a general anxiety related to the COVID-19 contagious risk of the hospital environment. As a matter of fact, during this year of pandemics, several case reports suggested a new, significant surge of post-AMI mechanical complications, sometimes describing patients admitted in too severe conditions to consider surgical repair a viable option, and therefore inevitably undergone an unfavorable outcome.

Therefore, we decided to involve the large network of European centers already participating to the "Caution Study 1", in order to study the impact of COVID-19 pandemics on the outcomes, incidence and treatments of post-AMI mechanical complications.

Detailed Description

Mechanical complications must be carefully searched for in any patient with an acute coronary syndrome and signs of cardiogenic shock, as prompt diagnosis and immediate surgery often represent the only effective treatment for such ominous conditions.

The management of patients with postinfarction mechanical complications requires the consideration of several factors: (i) the extremely poor prognosis without surgical treatment; (ii) the higher mortality risk associated with emergency surgery; (iii) the potential rapid deterioration of initially stable patients.

Data from the Society of Thoracic Surgeons National Database demonstrated an average 43% in-hospital/30-day mortality for surgical treatment of ventricular septal rupture. Data from the same registry on papillary muscle rupture showed a 30-day mortality of 20%. Matteucci et al. recently reported a 36.4% mortality rate for free wall rupture from the large CAUTION multicenter study.

Given the low incidence of these post-AMI mechanical complications, evidence-based therapeutic strategies remain controversial, and little is known on the early clinical results and late follow-up, with most information derived from small single-center experiences or national registries.

Therefore, we started the "Mechanical complications of acute myocardial infarction: an international multicenter cohort study" - (Caution Study 1), a retrospective, international multicenter clinical trial aimed at evaluating the survival, postoperative outcome and quality of life of patients undergone cardiac surgery for post-infarction mechanical complications starting from 2001.

The ongoing COVID-19 pandemics, however, has put an overwhelming pressure on the healthcare systems of many European countries. Such a situation has potentially led to delayed and impaired access to appropriate treatment for patients affected by other severe, non-COVID-19-related conditions, including cardiovascular diseases. This resulted in a reported lower admission, but higher mortality rate for AMI patients.This situation might be explained by many factors, including unavailability of early reperfusion therapy and late hospital presentation of AMI patients due to a general anxiety related to the COVID-19 contagious risk of the hospital environment.

"Mechanical complications of acute myocardial infarction: an international multicenter cohort study during COVID-19 pandemics" is a retrospective, international multicenter clinical trial aimed at evaluating the trend of incidence, types of treatment and survival of patients admitted to hospital with a diagnosis of post-infarction mechanical complications.
