Heart failure is extremely prevalent and is associated with significant mortality, morbidity and cost. Studies have already established mortality benefit with the use of neurohormonal blockade therapy in systolic failure. Unfortunately, physical signs and symptoms of heart failure lack diagnostic sensitivity and specificity, and medication doses proven to improve mortality ...

BACKGROUND: Cardiac rupture is an unusual cause of chest pain and sudden cardiovascular collapse. This diagnosis may be easily forgotten while managing a patient in extremis in the initial minutes of evaluation and resuscitation in the emergency department (ED). OBJECTIVES: To report the benefit of immediate bedside cardiac ultrasonography in ...

We report a case of sudden marked deterioration of ventricular stimulation threshold resulting in pacemaker failure 16 months after a ventricular septal lead implantation for atrioventricular block. Echocardiography revealed septal wall thinning at the electrode-tissue interface, which was not detected pre-operatively. Endomyocardial biopsy confirmed cardiac sarcoidosis. The increased threshold was ...

The cellular immunoprofile of cardiac dysfunctions and lesions of ischemic etiology are insufficiently studied to date, especially regarding the contribution of non-cardiomyocytic structures. Aiming to explore this immunoprofile, we used immunohistochemistry applied on embryonic, fetal and adult normal or ischemic myocardium. We observed a decrease of smooth muscle alpha-actin expression ...

Intramural hematoma in major coronary epicardial vessels is a rare cause of chest pain. Afflicted individuals may present with acute coronary syndrome (ACS) or even sudden cardiac death. Spontaneous, isolated intramural hematoma may occur in the absence of associated intimal dissection. In this situation, lesions may be angiographically indistinguishable from ...

We present two cases of cardiac tamponade presenting in the aftermath of cardiac surgery. We have briefly discussed the aetiology, presentation, diagnosis and management of the condition with emphasis on its atypical presentation in postoperative patients. A high index of suspicion and early access to echocardiography is necessary for prompt ...

A 41-year-old woman with idiopathic thrombocytopenic purpura and dyslipidemia abruptly developed vertigo, truncal ataxia and divergence paralysis. Cranial magnetic resonance imaging demonstrated the presence of infarction in the left superior paramedian mesencephalic artery involving the vicinity of the periaqueductal gray matter. The symptoms rapidly resolved under the administration of anti-platelet ...

High-output cardiac failure is rare in newborns. Emergent diagnosis and management of this pathology is crucial. We report the case of a child, currently 12-months old; obstetric background is non-contributory. Clinic observation on D1 was normal except for the presence of a systolic cardiac murmur; cardiological evaluation revealed mild ventricular ...

Heart failure patients with stable angina, acute coronary syndromes and valvular heart disease may benefit from revascularisation and/or valve surgery. However, the mortality rate is increased- 5-30%. Biventricular pacing using temporary epicardial wires after surgery is a potential mechanism to improve cardiac function and clinical endpoints. A multi-centred, prospective, randomised, ...

A 49-year-old woman who had idiopathic thrombocytopenic purpura was admitted to our hospital with severe chest pain. Electrocardiography revealed inferolateral myocardial infarction. The patient underwent immediate coronary angiography, which revealed thrombi in the left coronary system. Percutaneous intervention was not indicated, because the thrombi had occluded the distal segments of ...

Peripartum myocardial infarction is a rare event that is associated with high mortality rates. The differential diagnosis includes coronary artery dissection, coronary artery thrombosis, vascular spasm, and stenosis. Our evaluation of 2 cases over a 5-year time period has led to a hypothesis that peripartum myocardial infarction is an immune-mediated ...

Following a perinatal hypoxic-ischaemic insult, term infants commonly develop cardiovascular dysfunction. Troponin-T, troponin-I and brain natriuretic peptide are sensitive indicators of myocardial compromise. The long-term effects of cardiovascular dysfunction on neurodevelopmental outcome following perinatal hypoxic ischaemia remain controversial. Follow-up studies are warranted to ensure optimal cardiac function in adulthood. Cardiac ...

Cardiac monitoring of ventricular assist devices (VADs) is important for detecting heart failure risks, such as critical arrhythmia and ventricular fibrillation, and for supplying data that are useful for hemodynamic control. Specifically, impedance cardiograms (ICGs) are especially beneficial because they have no effect on the tissue or organs and can ...

BACKGROUND: In clinical heart failure (HF), inefficient propagation of blood through the left ventricle (LV) may result from suboptimal vortex formation (VF) ability of the LV during early diastole. We aim to (i) validate echocardiographic-derived vortex formation time (adapted) (VFTa) in control subjects and (ii) examine its utility in both ...

Acute coronary syndrome (ACS) is a significant cause of morbidity and mortality worldwide. The proper diagnosis of ACS requires reliable and accurate biomarker assays to detect evidence of myocardial necrosis. Currently, troponin is the gold standard biomarker for myocardial injury and is used commonly in conjunction with creatine kinase-MB (CK-MB) ...

Pacemaker telemetry reflects algorithm-dependent interpretations about the cardiac rhythm. For these data to be useful, it is necessary to recognize the limitations of each algorithm and its interactions with pacing and sensing parameters. We report on a case in which pacemaker Holter recording showed several episodes of nonsustained supraventricular tachycardia ...

Electrocardiogram (ECG) is a useful but imperfect investigation in the diagnosis and possible follow-up of structural heart disease such as ventricular hypertrophy. Different ECG criteria with different sensitivity and specificity are available to aid the detection of left or right ventricular hypertrophy. Subsequent echocardiography can help in the quantification of ...

Ischemia/reperfusion and hypoxia/reoxygenation of the heart both induce shedding of the coronary endothelial glycocalyx. The processes leading from an oxygen deficit to shedding are unknown. An involvement of resident perivascular cardiac mast cells has been proposed. We hypothesized that either adenosine or inosine or both, generated by nucleotide catabolism, attain ...

Limited and conflicting data exist on the diagnosis of cardiac allograft rejection with the use of echocardiography. The purpose of our study was to evaluate various systolic and diastolic indices, including newer tissue Doppler imaging techniques, in diagnosing cardiac allograft rejection. We prospectively performed 426 echocardiography studies at the time ...

Hyperthyroidism is associated with many heart diseases. Thyrotoxic state has a relationship with coronary spasm. We present a case of a non-menopausal woman with hyperthyroidism who complained of chest pain. The diagnosis of coronary spasm was confirmed by coronary angiography (CAG). She is treated well with anti-thyrotoxicosis and anti-anginal medication. ...

BACKGROUND: Pericardial effusion occurs frequently in patients with hypothyroidism and is typically mild. Although extremely uncommon, massive pericardial effusion can compromise hemodynamics and cause cardiac tamponade. Reduced plasma volume has been reported to induce cardiac tamponade in massive pericardial effusion, but to our knowledge, hypovolemia-induced cardiac tamponade has not been ...

We assessed the effect of extending the range of cardiovascular (CV) end points to include hospitalization for unstable angina and hospitalization for coronary revascularization (Extended Major Adverse Cardiac Event criteria (MACE)) in addition to the standard ones, namely, CV-related death, nonfatal stroke, and nonfatal myocardial infarction (Core MACE). The trials ...
