Background: Knowledge is limited concerning the type of symptoms and the time from onset of symptoms to first medical contact at first and second myocardial infarction in the same patient. Aim: This study aimed to describe the type of symptoms and the time from onset of symptoms to first medical contact in first and second myocardial infarctions in men and women affected by two myocardial infarctions. Furthermore, the aim was to identify factors associated with prehospital delays ≥2 h at second myocardial infarction. Methods: A retrospective cohort study with 820 patients aged 31–74 years with

Using a cohort from our hospital and published cohorts from Ireland, Uruguay, and Israel, we calculated odds of having an inferior wall as opposed to an anterior wall acute myocardial infarction among smokers and nonsmokers. Results. In our cohort, there was a higher proportion of smokers than nonsmokers in patients with inferior acute myocardial infarctions than in patients with anterior infarctions. This difference was also present in each of the other cohorts. O

Splenic and renal infarctions are embolic conditions which usually occur secondary to cardiac problems, thromboembolic systemic diseases, and infectious conditions such as sepsis. Trauma is a relatively rare cause of visceral infarctions. Traumatic segmental renal infarction associated with total splenic infarction is extremely rare. For detecting these visceral infarctions, contrast-enhanced computed tomography is essential, and a very careful examination is required for detecting very small infarctions and excluding total visceral infarctions.

OBJECTIVE Malignant internal carotid artery (ICA) infarction is an entirely different disease entity when compared with middle cerebral artery (MCA) infarction. Because of an increased area of infarction, it is assumed to have a poorer prognosis; however, this has never been adequately investigated. Decompressive craniectomy (DC) for malignant MCA infarction has been shown to improve mortality rates in several randomized controlled trials. Conversely, aggressive surgical decompression for ICA infarction has not been recommended. The authors sought to compare the functional outcomes and surviva

&lt;p&gt;The emergence of brain infarction depends to a great extent on the status of collateral blood circulation and is associated with hemodynamic instability. This kind of brain infarction is usually found in border vascular zones.

Liver infarctions are a very rare occurrence due to the multiple-source blood supply of the liver. The cause of hepatic infarction is unclear. When diagnosed, appropriate treatment of these infarctions is unknown. Herein we describe a case of acute liver infarctions, with no obvious cause, in a young woman. Work-up did not shed light on the underlying etiology. Treatment with anticoagulation was commenced in this case, with rapid improvement and a good clinical outcome. We suggest that anticoagulation can be administered to treat hepatic infarctions even in the absence of clear-cut thrombosis.

Abstract Three patients with unruptured fusiform aneurysms of the posterior circulation presented with nonhemorrhagic thalamic infarctions. All of the aneurysms were seen on enhanced computed tomographic (CT) scans preangiographically. Although unruptured fusiform aneurysms are probably a rare cause of nonhemorrhagic thalamic infarction, their importance lies in the therapeutic implications of this diagnosis. In patients with nonhemorrhagic thalamic infarction, we suggest careful scrutiny of the blood vessels on enhanced CT scans.

Pathological laughter is an uncommon symptom usually caused by bilateral, diffuse cerebral lesions. It has rarely been reported in association with isolated cerebral lesions. Midbrain involvement causing pathological laughter is extremely unusual. We describe three patients who developed pathological laughter after midbrain and pontine-midbrain infarction. In two patients a small infarction in the left paramedian midbrain was detected, whereas the third one sustained a massive bilateral pontine infarction extending to the midbrain. Laughter heralded stroke by one day in one patient and occurre

Abstract The role of the intrinsic coagulation system on the risk of myocardial infarction is unclear. In the Study of Myocardial Infarctions Leiden (SMILE) that included 560 men younger than age 70 with a first myocardial infarction and 646 control subjects, we investigated the risk of myocardial infarction for levels of factor XI (factor XIc) and factor XII (factor XIIc). Furthermore, the risks for factor VIII activity (factor VIIIc) and factor IX activity (factor IXc) were assessed. Factor XIc was 113.0% in patients compared with 109.8% in control subjects (difference, 3.2%; 95% CI, 1.1%-5.

Background: Acute myocardial infarctions are deadly to patients and burdensome to healthcare systems. Most recorded infarctions are patients’ first, occur out of the hospital, and often are not accompanied by cardiac comorbidities. The clinical manifestations of the underlying pathophysiology leading to an infarction are not fully understood and little effort exists to use explainable machine learning to learn predictive clinical phenotypes before hospitalization is needed.

The field of post-infarction myocardial ruptures is still a nearly blind spot of cardiology; there are many facts about it which are ambiguous and simply too vague. For example, the dispersion in frequency rate is quite self-explanatory: from 0 to 30 or even 35 per cent. A number of clinical studies concerning the 30 days mortality due to acute myocardial infarctions just ignores myocardial ruptures as being the cause of death. This probably comes from a certain confusion as the post-infarction myocardial ruptures and the cardiogenic shock have almost similar manifestations. However pathologis

These changes arc easily recognized and, with results of serum isoenzymes, physical assessment, and the patient’s history, aid in diagnosis.

Rupture of an atherosclerotic plaque in a coronary artery with subsequent thrombosis is the cause of most acute myocardial infarctions. Thrombolytics are the standard pharmacologic agents used to restore normal blood flow through the occluded coronary artery. While the use of thrombolytics has decreased both short-term and long-term mortality in patients presenting with acute myocardial infarction, these agents do have limitations. Combining glycoprotein IIb/IIIa receptor antagonists with thrombolytics is one strategy being investigated to try to improve outcomes after acute myocardial infarct
