Changes over time in the prevention of recurrent coronary artery disease in everyday practice.

Introduction: Patients with coronary artery disease (CAD) are at high risk of recurrent cardiovascular events, and risk factor control is crucial in this population.

Objectives: The aim of the study was to compare the implementation of the European Society of Cardiology guidelines regarding prevention of recurrent CAD in 2011 to 2013 with 2016 to 2017.

Patients And Methods: The study included 5 hospitals with cardiology departments serving the city of Kraków and its surrounding districts.

Temporal changes in the secondary prevention of coronary artery disease in patients following myocardial revascularization.

Introduction: Well-organized, effective secondary prevention of coronary artery disease (CAD) has a potential to improve the patients' prognosis following myocardial revascularization procedures.

Aim: To evaluate overtime changes in the implementation of the ESC guidelines for secondary prevention by assessing control of the main risk factors and the rate of cardioprotective drug use in patients following myocardial revascularization procedures.

Material And Methods: Patients aged < 81 years who had been hospitalized for a myocardial revascularization procedure in five hospitals serving Krakow and surrounding districts were recruited and interviewed 6-18 months following discharge.

[QRS alternans during ventricular tachycardia].

We present electrocardiograms of a 70-year-old man with a history of inferior wall myocardial infarction. Since the infarction he had frequent episodes of ventricular tachycardia that was on many occasions misdiagnosed as either supraventricular tachycardia or atrial flutter. We contribute the mistakes to the presence of relatively narrow QRS complexes and QRS alternans that imitated fusion beats.

[Variant Brugada syndrome--mild ST segment elevation in inferior leads and aborted sudden cardiac death].

We describe a case of an otherwise healthy 48-year-old man who survived aborted sudden cardiac death (SCD). His ECG showed ST segment elevation in inferior leads, therefore an acute coronary syndrome was suspected. However, serial troponin T and CPK-MB were negative, echocardiogram was unremarkable and exercise test was negative.
