The importance of thrombolytic therapy within the first 3 hours of onset of symptoms of an acute stroke has been stressed, and in consequence, the diagnosis is most commonly made based on clinical grounds. Intracranial hemorrhage is the major life-threatening complication with the use of thrombolytic therapy. Because of the ...

Sudden death is an important but widely under-recognised consequence of stroke. Acute stroke can disturb central autonomic control, resulting in myocardial injury, electrocardiographic abnormalities, cardiac arrhythmias, and ultimately sudden death. Experimental and clinical evidence suggests that autonomic imbalance is more frequent after infarcts involving the insular cortex, a crucial region ...

Carbon monoxide (CO) is a well-known chemical asphyxiant, which causes tissue hypoxia with prominent neurological and cardiovascular injury. After exposure to CO, several cardiac manifestations have been reported, including arrhythmias, acute myocardial infarction, and pulmonary edema. However, an ST elevation myocardial infarction (STEMI) due to CO poisoning is a very ...

Alcohol is well-recognized systemic toxin that causes numerous adverse effects, including psychosocial problems, fatal myocardial infarction, stroke and atherosclerosis. The intra-abdominal complications caused by acute alcohol consumption have not been defined. We report an 80-year-old man with sub-acute small bowel and colonic ischemia after heavy alcohol intake in one sitting. ...

Numerous reports have demonstrated that periodontal bacteria are present in plaques from atherosclerotic arteries. Although periodontitis has recently been recognized as a risk factor for coronary artery disease, the direct relationship between periodontal bacteria and coronary artery disease has not yet been clarified. It has been suggested that these bacteria ...

ABSTRACT: BACKGROUND: Pre-hospital electrocardiogram (ECG) transmission to an expert for interpretation and triage reduces time to acute percutaneous coronary intervention (PCI) in patients with ST elevation Myocardial Infarction (STEMI). In order to detect all STEMI patients, the ECG should be transmitted in all cases of suspected acute cardiac ischemia. The ...

Deciding how to treat acute myocardial infarction (MI) with myocardial bridge is difficult because stent fracture and early restenosis are frequently reported. We present a 50-year-old female patient with acute MI and myocardial bridge. Optical coherence tomography (OCT) and fractional flow reserve were used to reach a decision on treatment.

Acute myocardial infarction resulting from an occlusive thrombus is recognized on an electrocardiogram by ST-segment elevation. The earlier the reperfusion, the greater the benefit, and the time to treatment is now considered to indicate the quality of care. In the current era when percutaneous interventions are carried out so readily, ...

Cardiogenic shock is a serious complication of acute myocardial infarction and occurs as a consequence of acute left ventricular failure and subsequent inappropriate tissue perfusion. While its incidence has been reported to be as high as 10% in the late 90ties, it has been steadily declining to currently less than ...

Primary percutaneous coronary intervention (PCI) is currently the preferred revascularization strategy in acute trasmural myocardial infarction (AMI). In this setting, about one half of patients will be diagnosed with concomitant multivessel (MV) coronary artery disease, associated with a multitude of negative prognostic factors but also still an independent predictor of ...

Alterations in the autonomic nervous system after ascent to high altitude may be related to the development of acute mountain sickness (AMS). So far, the time course of cardiac autonomic modulation in relation to AMS development during the early hours at altitude is not well established. As AMS develops sometimes ...

Extracorporeal membrane oxygenation is an established treatment for acute respiratory failure, or low cardiac output syndrome. This can be veno-venous, in which de-oxygenated blood is drained from the venous system and oxygenated before being returned to the venous system, and veno-arterial where the re-oxygenated venous blood is returned to the ...

Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first. Most cases of cardiogenic UPE occur in the right upper lobe and are caused by severe mitral regurgitation (MR). We present an unusual case of right-sided UPE in a patient with cardiogenic shock due ...

BACKGROUND: Daylight saving time shifts can be looked upon as large-scale natural experiments to study the effects of acute minor sleep deprivation and circadian rhythm disturbances.

We present the case of a 42-year-old Japanese woman who developed acute heart failure after chemotherapy with epirubicin for breast cancer. Echocardiography revealed a cardiac dysfunction with left ventricular thrombus. Serial serum troponin T tests were positive over a 5-week period, and an endomyocardial biopsy demonstrated ultrastructural lesions which were ...

Although both coronary artery dissection and heparin-induced thrombocytopenia may provoke myocardial infarction, it is extremely rare for both conditions to develop simultaneously in a single patient. We report a case of a 69-year-old woman who sustained a head-on motor vehicle accident with associated chest trauma. During a subsequent hospitalization, she ...

The role of histamine as a newly recognized sympathetic neurotransmitter has been presented previously, and its postsynaptic effects greatly depended on the activities of sympathetic nerves. Cardiac sympathetic nerves become overactivated under acute myocardial ischemic conditions and release neurotransmitters in large amounts, inducing ventricular arrhythmia. Therefore, it is proposed that ...

Population based study using person linked routine hospital ...

Acute myocardial infarction is sometimes complicated in patients with coronary spastic angina. The mechanisms are known to be plaque rupture and thrombosis induced by spasm, and reduced coronary flow due to prolonged spasm. We describe the case of a 45-year-old woman with coronary spastic angina who had a complication of ...

T2w-CMR is used widely to assess myocardial edema. Quantitative T1-mapping is also sensitive to changes in free water content. We hypothesized that T1-mapping would have a higher diagnostic performance in detecting acute edema than dark-blood and bright-blood T2w-CMR. We investigated 21 controls (55 ± 13 years) and 21 patients (61 ± 10 years) with Takotsubo cardiomyopathy ...

In acute myocardial infarction (AMI), both tissue necrosis and edema are present and both might be implicated in the development of intraventricular dyssynchrony. However, their relative contribution to transient dyssynchrony is not known. Cardiovascular magnetic resonance (CMR) can detect necrosis and edema with high spatial resolution and it can quantify ...

The primary purpose was to compare the odds of acute coronary syndrome-pertinent diagnostic testing between self-reported cocaine users and non-users at the turn of the century. The secondary purpose was to compare the odds of acute coronary syndrome outcomes between cocaine users and non-users. Nested matched case-control study using data ...

Remote ischemic conditioning (RIC) is a therapeutic strategy for protecting organs or tissue against the detrimental effects of acute ischemia-reperfusion injury (IRI). It describes an endogenous phenomenon in which the application of one or more brief cycles of non-lethal ischemia and reperfusion to an organ or tissue protects a remote ...

Platelets play an important role in the development of acute coronary syndromes. Evidence indicates that platelet-inhibiting drugs, such as glycoprotein IIb/IIIa inhibitors, can be beneficial when they are administered at the time of primary percutaneous coronary intervention for acute ST-segment-elevation myocardial infarction. However, an associated increase in the risk of ...

Interatrial block is an abnormally delayed atrial activation, characterized at ECG by prolonged P-wave duration (more than 110 ms), irrespective of morphology. We report the case of a patient with acute decompensated severe congestive heart failure, that at hospital admission showed a prolonged P-wave, which reverted after diuretic therapy. The ...

Cardiac biomarkers (CB) were first developed for assisting the diagnosis of cardiac events, especially acute myocardial infarction. The discoveries of other CB, the better understanding of cardiac disease process and the advancement in detection technology has pushed the applications of CB beyond the 'diagnosis' boundary. Not only the measurements of ...

Cardiac echinococcosis rarely mimics acute coronary syndrome.
