To assess the impact of summer heat waves on key parameters of oxidative stress in patients with coronary heart disease. ⋯ Changes in the key parameters of oxidative stress in patients with ischemic heart disease during summer heat waves are comparable to those in patients without ischemia, however significantly greater inhibition of GSH-Px activity and significantly lower increase in Cu,Zn-SOD activity was noted. These results may indicate misregulation of free radical processes in patients with ischemic heart decease.

Cardiac myxoma is the most common primary benign cardiac tumor (up to 50% of all primary cardiac neoplasms). The implementation of the modern imaging techniques into the clinical practice, particularly, 2D echocardiography, computed tomography and magnetic resonance tomography (MRI) results to the prompt diagnosis of the myxoma. However, the absence of specific clinical features, insufficient awareness of this condition among the physicians along with a rare prevalence, may lead to a misdiagnosis. This case report is notable for the relatively late diagnosis of a giant left atrial myxoma due to a number of circumstances but with successful surgical treatment.

Recently, the role of cardiac magnetic resonance imaging (cardiovascular magnetic resonance) in the diagnosis of coronary artery disease and acute myocardial infarction has increased significantly. This method is defined as the gold standard for differentiation between ischemic vs non-ischemic and acute vs chronic myocardial injury. This part of the review summarizes the main methods of cardiovascular magnetic resonance, its safety, indications and contraindications.

The tachycardia-induced cardiomyopathy is a rare case of reversible heart failure and left ventricle disfunction. The diagnostic approach and treatment strategy are described in this article. Also the clinical case of heart failure compensation in the patient with left ventricle dilatation and atrial flutter after the reverse to sinus rhythm is after catheter ablation presented.

There are presented the literature data and a description of the clinical course of the disease in isolated/predominant cardiac amyloidosis. Amyloid cardiomyopathy is the most common phenocopy of hypertrophic cardiomyopathy. The modern possibilities of non-invasive diagnostics using osteoscintigraphy for the differential diagnosis between amyloid cardiomyopathy caused by AL- and transthyretin amyloidosis are described in detail.
