Kounis syndrome has been known as allergenic angina and/or allergenic myocardial infarction following an allergic reaction. Probable allergic insults usually include drugs, latex, and food. Although ceftriaxone administration has been associated with various allergic reactions such as urticaria, angioedema, erythema, rash and anaphylactic shock, as far as we know, there ...

Cardiac echinococcosis rarely mimics acute coronary syndrome. The diagnosis of cardiac hydatid cyst might be difficult on account of varying clinical presentations and nonspesific symptoms. A 75-year-old female was admitted to our hospital with typical chest pain. The patient had no history of previous cardiac symptoms or any illness leading to ...

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 ...

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 ...

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 ...

Anthracyclines are potent cytostatic drugs, the correct dosage being critical to avoid possible cardiac side effects. ABCC1 [ATP-binding cassette, sub-family C, member 1; also denoted as MRP1 (multidrug resistance-associated protein 1)] is expressed in the heart and takes part in the detoxification and protection of cells from the toxic effects ...

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 ...

Heart failure is a syndrome in which myocardial function is incapable of providing for normal physiologic needs. In the acute care setting, cardiac dysfunction primarily manifests with volume perturbations and presents with signs and symptoms of vascular congestion. Thus, in acute heart failure volume assessment is crucial in diagnosing and ...

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 ...

Platelets play a critical role in the pathophysiology of acute coronary syndrome and thromboembolic complications associated with atrial fibrillation. Despite the development of newer and more potent antiplatelet agents, aspirin remains the cornerstone of antithrombotic therapy. Clinical trials conducted over the past decades have clearly established the safety and efficacy ...

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 ...

Acute kidney injury (AKI) is a risk factor for long-term adverse outcomes, including acute myocardial infarction and death. However, the relationship between severity of AKI and in-hospital outcomes in the setting of acute myocardial infarction has not been well documented. The study population (n = 59,970) was drawn from the ...

After the Norwood procedure for palliation of hypoplastic left heart syndrome, there is still significant interstage and late mortality with often unclear etiology. An important, but possibly under-recognized complication of the Norwood operation is the potential for coronary insufficiency from pre-coronary stenosis due to kinking or scarring at the anastomosis ...

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. He developed anasarca, malabsorption, malnutrition and left ventricular failure. Duodenal biopsy revealed abundant rhabditiform larvae of Strongyloides stercoralis. ...

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. ...

Myocardial ischemia in pregnancy poses a significant challenge for the anesthesiologist. It is a relatively rare disorder (approximately 180 cases published in the indexed literature since 1922) but it carries high mortality. Diagnosis is frequently hampered by diminished sensitivity of several testing modalities conventionally used to diagnose myocardial ischemia. The ...

Cardiogenic shock is characterized by inadequate tissue perfusion due to cardiac dysfunction and is the leading cause of death in patients hospitalized with acute myocardial infarction. Mortality from cardiogenic shock still remains high. The development of cardiogenic shock is rarely unexpected; most patients who develop cardiogenic shock do so within ...
