Diagnosing and selecting an appropriate treatment strategy for left main coronary artery (LMCA) obstruction is very important. Although this disease is not frequently encountered, it can cause severe hemodynamic deterioration resulting in a less favorable prognosis without a suitable management approach. Another aspect of LMCA that we must not overlook ...

The short inversion time inversion recovery (STIR) black-blood technique has been used to visualize myocardial edema, and thus to differentiate acute from chronic myocardial lesions. However, some cardiovascular magnetic resonance (CMR) groups have reported variable image quality, and hence the diagnostic value of STIR in routine clinical practice has been ...

A patient with mitral stenosis and multiple left atrial thrombi underwent valvuloplasty and thrombectomy. While closing the sternum after completing the cardiopulmonary bypass, a new left atrial thrombus was detected by transesophageal echocardiography. We used heparin for the prevention of new thrombus formation and closed the wound after meticulous bleeding ...

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 ...

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 ...

Current cardiovascular magnetic resonance (CMR) methods, such as late gadolinium enhancement (LGE) and oedema imaging (T2W) used to depict myocardial ischemia, have limitations. Novel quantitative T1-mapping techniques have the potential to further characterize the components of ischemic injury. In patients with myocardial infarction (MI) we sought to investigate whether state-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 ...

Cardiac ischemia-reperfusion (I-R) injury occurs upon prompt restoration of blood flow to the ischemic myocardium after an acute myocardial infarction. Interestingly, many of the features of I-R injury are related to impaired mitochondrial signaling and mitochondrial dysfunction. Restoring cardiac energy bioavailability and reduction-oxidation (redox) signaling are therefore important in recovery ...

Strongyloidiasis in an immunocompromised patient has the potential to be life threatening. We describe a boy who was on steroids for acute demyelinating myelitis and receiving antibiotics for E.coli UTI and meningitis.

We report the case of a 72-year-old man with ST-elevation acute myocardial infarction and severe intra-ventricular gradient (>40 mmHg), who died with left ventricular rupture (LVR). We postulate that severe intra-ventricular gradient detectable at admission may be related to subsequent LVR and proposed as a risk factor for LVR.

Reperfusion therapy has become an established treatment for ST-segment elevation acute myocardial infarction (STEMI), increasing the need for early diagnosis and early treatment. Despite the development of diagnostic strategies, the electrocardiogram (ECG) plays a central role in the diagnostic pathway for STEMI because it is inexpensive, readily available, and noninvasive. ...

Acute myocardial infarction (AMI) due to coronary artery disease is a leading cause of death in both the developed and developing countries. The advent of coronary care units and early reperfusion therapy (Thrombolytic and Percutaneous Coronary Intervention) has substantially decreased in-hospital mortality rates and has improved the outcome in survivors ...
