Hemorrhagic stroke during the acute phase of myocardial infarction: a rare and difficult situation to manage.

Given the ischemic risk due to the hypercoagulability associated with acute coronary syndromes, the administration of antiplatelet and antithrombotic agents is necessary to prevent intracoronary and postprocedural thrombosis during percutaneous coronary interventions. However, the risk of bleeding, hemorrhagic stroke included, is real, although it has a lower prevalence, and it complicates the management of the coronary event if it happens. We report the case of a 66 years old patient with no prior pathological history who was initially admitted for acute coronary syndromes, complicated by paroxysmal atrial fibrillation that was successfully thrombolysed. Subsequently, the patient benefited from a drug-eluting stent angioplasty of the proximal circumflex artery, performed within 24 hours after the symptomatology onset. Following angioplasty, the patient presented with a left parietal intraparenchymal hematoma not indicating surgery. The double antiplatelet therapy was consequently withdrawn. Two days later, the patient presented with an ST-segment elevation infarction recurrence, inciting the resumption of the dual antiplatelet aggregation therapy. On evolution, the neurological state was still stable with a stationary aspect of the hematoma on cerebral imagery but without angina recurrence or electrocardiographic modifications. Hemorrhagic complications' occurrence following thrombolysis or angioplasty for ST-segment elevation infarction challenges the short and long-term management of the disease and must push practitioners to better weigh the risks and benefits before any medication administration decision.

Acute myocardial infarction complicated by severe left ventricle systolic dysfunction in a young patient after Covid 19 vaccination: a case report.

We report the case of a 23 years old patient who developed an acute myocardial infarction one day after his second dose of COVID-19 BIBP vaccination, complicated by severe left ventricle systolic dysfunction with an ejection fraction measured at 32%, associated with left ventricular wall motion abnormalities well evolved under treatment of heart failure with reduced EF combining :angiotensin-converting enzyme inhibitor, beta blocker, mineralocorticoid receptor antagonists and sodium-glucose cotransporter 2 inhibitors. Coronary arteries were normal at angiography suggesting initially the diagnostic of myocarditis. Therefore, a cardiac magnetic resonance imaging was performed to confirm the latter, which showed an image consistent with a recent left ventricular subendocardial infarction, remarkably prominent in the left anterior descending artery territory and the absence of signs of myocarditis. The patient had no previous past medical history or other clinical features explaining this coronary event onset. Thus, the vaccine was potentially to be implicated in the pathophysiology of the event. Overall, complications associated with COVID-19 vaccines are extremely rare, and their benefit is well established. That's why they continue to be recommended by public health experts despite of their rare side effects.

Association of pulmonary embolism and acute coronary syndrome during COVID-19 infection: Case report and a brief review.

INTRODUCTION AND IMPORTANCE: COVID 19 infection is considered a potentially serious disease since it is responsible for important respiratory and cardiovascular complications with a high morbid-mortality. CASE PRESENTATION: We report the case of a 54-year-old diabetic patient with hypertension who was admitted for heart failure with a reduced LVEF of 23% triggered by a pulmonary embolism and an acute coronary syndrome in the context of COVID-19 infection. CLINICAL DISCUSSION: Indeed, these complications may be secondary to a prothrombotic and hypercoagulable state as well as endothelial dysfunction caused by the vascular and systemic inflammation and cytokine storm induced by SARS-CoV-2. Although the clinical polymorphism of COVID 19 infection is recognized, the association of myocardial ischemia with pulmonary embolism is uncommon and of adverse prognosis. This justifies a rapid and adapted multidisciplinary management. CONCLUSION: In the absence of contraindication, thromboprohylaxis should be initiated for all hospitalized patients with COVID-19 to minimize the risk of thromboembolic complications.

Multiple cardiovascular complications of COVID-19 infection in a young patient: a case report.

COVID-19 infection is responsible for many complications, which can lead to a high risk of mortality in some patients. Among them are cardiovascular complications which are classified as the most severe. We report a case of a young woman, with no relevant pathological history, admitted for COVID-19 infection, complicated by myocarditis with severe ventricular dysfunction, cardiogenic shock and a large thrombosis into the left ventricle (LV) that was responsible for a left lower limb ischemia associated with a deep venous thrombosis of right lower limb.
