Filter by:With the appearance of the new SARS-COV2 virus, additional challenges are being imposed on the medical community after the resolution of acute COVID-19 illness, resulting in specific pathophysiologic mechanisms that while acutely damage the lung parenchyma might chronically impact the cardiopulmonary system. This study aims to investigate changes after mild COVID-19 illness in echocardiographic indices at rest and stress.
The echocardiographic indices of the right ventricle function vary significantly with demographic and anthropometric of each population factors and are associated with poor prognosis in several cardiovascular diseases. This study aims to investigate exercise-induced changes in echocardiographic indices of the right ventricle function in healthy volunteers and establish the reference values to the Mexican population.
Multivessel disease has been reported to occur between 40 and 60% of patients with ST-segment elevation myocardial infarction (STEMI) and has been associated to a worse prognosis. Multivessel revascularization offers a myriad of potential advantages as enhance of the collateral blood flow, greater myocardial salvage, the stabilization of other lesions that can be potentially vulnerable, and the achievement of a complete revascularization, factor that is associated with a better prognosis. On the other hand, the prolongation of procedural duration, the hazard of contrast induced nephropathy and the peri-procedural complications can limit the widespread of this practice. To date, very few observational studies have focused in the multivessel revascularization with disparity of results. Whereas ones have observed an increase of adverse cardiovascular events and thus not recommend it, others have shown neutral results. Stress echocardiography has been shown to be an adequate technique for the diagnosis of coronary artery disease and could be an appropriate tool for selecting the lesions that need to be revascularized because they induce large areas of ischemia. However, this technique has also limitations like the high operator-dependence. Therefore, the investigators sought to study if the complete multivessel revascularization of patients with STEMI treated by means of primary percutaneous coronary intervention (PCI) has an impact on prognosis compared to a strategy of treating only those non-culprit lesions that produce large areas of ischemia in a stress test.
