Acute myocardial infarction (AMI) is a challenging cardiovascular disease leading to a high rate of mortality. Some cardiomyocytes in AMI were affected by ischemia and necrosis, resulting in a decrease in myocardial contractility, an acute proinflammatory response, and an increase in sympathetic tone. In the meantime, proinflammation and endothelial dysfunction are induced by high blood pressure variability (BPV), which increases left ventricular workload, heart rate, and myocardial oxygen demand. As a result, a high BPV and the pathological effects it causes are likely to affect the onset of acute cardiac complications in AMI and the physiological function of the heart [1]. Patients Pulse changeability (BPV) has been fundamentally concentrated on through the crystal of congestive cardiovascular breakdown (CHF) and hypertension, yet not in that frame of mind of an intense coronary condition (ACS). This study means to explore the relationship between transient BPV and major unfavorable heart occasions (MACE) in AMI patients. The following order can be used to define MACEs: Death > shock > cerebrovascular stroke > heart failure > hypertensive crisis > life-threatening arrhythmias .This prospective study used the weighted standard deviation of 24-hour ambulatory blood pressure monitoring readings to include 74 patients who were hospitalized in the cardiology department at ARRAZI hospital MOHAMED VI, MARRAKECH between September 2022 and February 2023. Results: The average systolic BPV value which was estimated as standard deviation (SD) and average real variability (ARV) was more significant in the MACE group than in the non-MACE group. Systolic SD and systolic ARV in the MACE group were 12,78 mmHg and 11,61 mmHg respectively. In the non-MACE group, systolic SD and systolic ARV were 10.45 mmHg and 7,23 mmHg respectively. There was no significant association between BPV and MACE. However, there were significant differences between systolic ARV in patients with hypertension who experienced MACE and patients without hypertension who experienced MACE, unlike patients who didn’t experienced MACE for whom the ARV was nearly the same for patient with and without HBP. Conclusion: MACE was higher in the group BPV of AMI patients than that of non-MACE AMI patients. There was no significant association between BPV ??and MACE during the acute phase of AMI, however the BPV was significantly more important for HBP patient who experienced MACE, which leads us to think that the screening of BPV in HBP patient may by a predictive factor for the development of MACEs.

Introduction: Infective endocarditis (IE) is a rare but potentially serious disease. It causes a high mortality and a high level of morbidity and complications. Its epidemiological, clinical and microbiological characteristics have changed in recent years. The Aim of our Work: Is to study the epidemiological, clinical, bacteriological, ultrasonographic, therapeutic and evolutionary data of IE between January 2017 and October 2022 in the Mohammed VI University Hospital and to compare them to the global profile. Materials and Methods: Retrospective study including 110 patients hospitalized for a definite IE, according to the modified DUKE criteria, in the cardiology department of the Mohammed VI University Hospital over a period of 5 years and 10 months from January 2017 to October 2022. Results: The average age of our patients was 43 years with a male predominance. The bacterial graft was on native valve in 80% with predominance of rheumatic origin (69%), on cardiac prosthesis in 10% of patients, on healthy heart (4%) and congenital heart disease (6%). The most frequent portal of entry was dental (30%). Blood cultures were positive only in 33% of patients, isolating a staphylococcus (16%), a streptococcus (14%) and a GNB (3%). Transthoracic echocardiography (TTE) showed vegetation in 108 cases, valve perforation in 7 cases, cord rupture in 1 patient and perivalvular abscess in 10 cases. Seventy-seven percent of patients had surgical treatment with a mean delay of 29 days. The overall mortality was 24% with heart failure (p<0.001), renal failure (p=0.004) and neurological complications (p=0.002) as predictive factors of mortality. Conclusion: Infective endocarditis remains a real health problem with a consequent mortality and morbidity. The population is often young, revealing the IE by complications; its prevention is the best way to improve its prognosis.

Behcet’s disease is a systemic vasculitis of the vessels for all calibers, touching arterial and venous territories. The causes of disease are unknow. BD reaches young age subjects from 10 to 45 years and affects both men and women. BD is ubiquitous but more frequent in patients from Mediterranean basin, the middle East and Asia. The diagnosis of BD is essentially clinical. The diagnostic criteria make it possible to carry the diagnosis with good sensitivity and specifity. BD evolves by recurrent inflammatory attack. BD can affect all of the organs; cardiacs manifestations are dominated by intracardiac thrombosis, the damage of three tunics, coronaryarteritis with or without myocardial infarction, coronaries aneurysms and endomyocardial fibrosis. The vascular manifestations are dominated by arterial or venous thrombosis. The presence of dilated cardiomyopathy with reduced left ventricular ejection fraction is rare. It can be explained by ischemic or inflammatory origin by cytokines. We report a case of young woman aged of 33 years to the history of 3 episodes of bipolar aphtae which presented dilated cardiomyopathy with reduced left ventricular function, biventricular thrombosis, bilateral distal pulmonary embolism with pulmonary infarction.
