Active clinical trials for "Infarction"

While perinatal ischemic stroke is the most frequent form of childhood stroke, early determinants of outcome remain poorly understood. Two main structural biases limit the accuracy of most studies: heterogeneity of the population and short follow-up. Perinatal ischemic stroke includes several conditions that differ in pathophysiology and timing of occurrence. Yet, it is not surprising that risk factors and outcome depend primarily on the type of stroke. Age at evaluation also plays a major role after a neonatal insult. Even though the original lesion is static and focal in perinatal stroke, its consequences grow over time within the maturing brain and affect all fields of neurodevelopment. The objective of the AVCnn study was to delineate the determinants, clinical and imaging presentation, mechanism, and long term outcome of a category of perinatal stroke (neonatal arterial ischemic stroke: NAIS). This led to the AVCnn cohort, which now gives us the opportunity to regularly monitor a large cohort of children having suffered an NAIS.

Today the treatment of ischemic stroke in acute phase is based on medicinal or endovascular revascularization. Cerebral MRI sequences help the diagnostic. This procedure uses deoxyhemoglobin as an endogenous tracer. This is also a scorer of cerebral ischemia and the increase lets visualized transcerebral veins in the suffering zone giving a brush aspect. Several studies show the interest of this sign and conclude that deoxyhemoglobin presence is a predictive factor of cerebral ischemia. The aim of the study is to evaluate this brush-sign and correlate it with the prognosis retrospectively.

The purpose of the study is to assess the prevalence and the prognostic value of non-invasive indexes and programmed ventricular stimulation for sudden cardiac death in post-myocardial infarction (MI) patients with left ventricular ejection fraction (LVEF)>40%.

The purpose of this study is to compare optical coherence tomography (OCT) scans performed in the same coronary artery with two different OCT systems (Lunawave and OPTIS) before and after implantation of stents or bioresorbable scaffolds.

A single-center, prospective case series clinical study consecutively enrolling up to 10 patients with expected duration of 12 months or less. The study objectives are to evaluate retention and the feasibility of integrating therapeutic hypothermia using the ZOLL IVTM System.

Metabolic syndrome (MS) has been reported as a risk for cardiovascular events. The aim of the present cohort study is to investigate whether ACEi therapy reduces the rate of periprocedural myocardial injury (PPMI) after elective percutaneous coronary intervention (PCI) among patients with metabolic syndrome.

The aims of the present study are to evaluate the information obtained by the EarlySenese monitoring system and examine correlation of the obtained data and clinical events.

The purpose of this study is to determine if a sizable myocardial infarction (heart attack) results in negative changes to renal structure and function (i.e. has a negative impact on the kidneys). To determine if the renal response to a myocardial infarction is a predictor of the patients future health.

Acute coronary syndromes (ACS) represent the leading cause of death in France. Their incidence is increasing due to population aging and to the persistence of cardiovascular risk factors. Currently, revascularization surgery remains outside the emergency treatment, because early performed, it tends to lead to extension and hemorrhage of the infarcted area, because of the CPB, aortic clamping, cardioplegia, and other heart manipulation. However, CABG are indicated as an emergency in some situations of STEMI: Threat of infarction of an extended territory without favorable anatomy to angioplasty, anatomy not favorable to angioplasty associated with cardiogenic shock or persistent ischemia, acute complications of myocardial infarction (massive mitral insufficiency, interventricular communication, parietal rupture) requiring surgery under CPB with concomitant bypass surgery or failure of angioplasty (proximal coronary dissection). Operative mortality is high; 15 to 20% for patients operated 12 to 48 hours after AMI and 4-5% for those operated after 48 hours. Nevertheless, it seems legitimate to study if there would be a place for primary surgical revascularization in case of patient with hemodynamically stable ACS, in order to limit myocardial ischemia, spread of necrosis, to limit the risk of recurrence, and the consequences of low cardiac output. Performing a complete early surgical revascularization could limit the ischemia-reperfusion syndrome and anticipate the occurrence of cardiogenic shock.

The study intends to provide important data on whether the noval method using quantitative flow ratio could predict microvascular dysfunction.
