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. Consecutive patients with established CAD were interviewed 6 to 18 months after hospitalization in the years 2011 to 2013 and 2016 to 2017. RESULTS: We examined 616 patients in 2011 to 2013 and 388 in 2016 to 2017 (mean [SD] age, 64.7 [8.8] years vs 66.4 [8.4] years; P <0.01). After adjusting for covariates, the proportion of patients with high blood pressure decreased by 8.9% (95% CI, -15.6% to -2.1%) and the proportion of patients with high level of low­ density lipoprotein cholesterol declined by 9.5% (95% CI, -16.7% to -2.2%) in 2016 to 2017 compared with 2011 to 2013, whereas the proportion of smoking patients (-0.2% [95% CI, -6% to 5.5%]) and those with high glucose levels (3.9% [95% CI, -2.2% to 10%]) and a body mass index of 25 kg/m2 or greater (3.8% [95% CI, -3.9% to 11.6%]) did not change. More patients were prescribed antiplatelets, ß­ blockers, angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, calcium antagonists, and anticoagulants in the second period. CONCLUSIONS: We observed an increase in the proportion of patients with CAD who were prescribed cardiovascular drugs, and consequently a slight improvement in the control of their blood pressure and low­ density lipoprotein cholesterol. No changes were found regarding other main risk factors.

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. Their personal medical history, medication use and control of the main cardiovascular risk factors were evaluated using a standard questionnaire in 2006-2007, 2011-2013, and 2016-2017. The same five hospitals took part in surveys on each occasion. RESULTS: We examined 260 patients in 2006-2007, 200 in 2011-2013 and 190 in 2016-2017. We noted a significant difference in the management of surveys participants: 62% underwent percutaneous coronary intervention (PCI) and 38% coronary artery coronary artery bypass grafting (CABG) in 2006-2007 whereas the corresponding proportions in 2016-2017 were 90% and 10%. The proportion of patients who did not achieve target blood pressure (according to ESC guidelines valid at the time of each survey) in 2006-2007, 2011-2013 and 2016-2017 was 53.5%, 52.3%, and 38.9%, respectively, the proportion of those who did not achieve the LDL cholesterol target (according to ESC guidelines valid at the time of each survey) was 36.3%, 64.0%, and 61.7%, respectively, and the proportion of those with high fasting glucose was 12.6%, 14.6%, and 19.7%, respectively. The proportion of smokers was 16.2%, 19.5%, and 16.8%, whereas 30.5%, 28.6% and 40.5% of patients were obese in 2006-2007, 2011-2013 and 2016-2017, respectively. The proportion of patients taking antiplatelets (91.8% vs. 92.0% vs. 96.3%), ß-blockers (90.3% vs. 87.5% vs. 92.6%), and lipid-lowering drugs (88.7% vs. 91.0% vs. 93.7%) did not change significantly.Conclusions: The analysis of three multicenter surveys provides evidence of the considerable potential for a further reduction in cardiovascular risk in patients following elective myocardial revascularization in Poland.

[QRS alternans during ventricular tachycardia]. / Naprzemiennosc zespolów QRS podczas czestoskurczu komorowego.

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. The QRS morphology similar to that seen in idiopathic ventricular tachycardia suggested participation of the Purkinje fibers of the posterior fascicle in the reentrant circuit. The arrhythmia was ablated with single radiofrequency current application in the mid-paraseptal area of the left ventricle.

[Variant Brugada syndrome--mild ST segment elevation in inferior leads and aborted sudden cardiac death]. / Wariant zespolu Brugadów--chory z uniesieniem odcinka ST w zakresie sciany dolnej i naglym zatrzymaniem krazenia.

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. On the basis of electrophysiological study, positive ajmaline test, persistent ST segment elevation in inferior leads and other clinical features (PQ interval of 240 ms, family history of SCD) a diagnosis of variant Brugada syndrome was made. Persistent ST segment elevations in inferior leads can be a marker of variant Brugada syndrome.
