Randomized Controlled Trial
Short-term efficacy and safety of three different antiplatelet regimens in diabetic patients treated with primary percutaneous coronary intervention: a randomised study.
This study aimed to investigate the efficacy and safety of dual and triple antiplatelet therapy (DAPT and TAPT) in patients with diabetes and acute ST segment elevation myocardial infarction (D-STEMI), who had undergone primary percutaneous coronary intervention (PCI). ⋯ TAPT effectively improved the TIMI blood flow and TMPG and reduced the occurrence of MACE. Ticagrelor was more effective than clopidogrel in TAPT; however, when using the combination of aspirin, ticagrelor, and tirofiban, close monitoring is required for possible bleeding complications.

Clinical studies in humans have shown the site of atrial stimulation to influence atrioventricular (AV) conduction times and refractory periods, the demonstration of dual AV nodal (AVN) pathways, and induction of AVN reentry. These studies often found conflicting results. Moreover, among enrolled patients a minority of them were found to have AVN reentrant tachycardia (AVNRT). ⋯ Rightward and leftward AVN extensions are regular features of the AV node. Their different electrophysiological properties lead to variation in the demonstration of discontinuous AVN conduction and AVNRT during right and left atrial pacing. Despite the observation that the left AVN extensions could compose the entry point to the reentrant circuit, there is no evidence that they constitute the critical component of sustained typical AVNRT.

Patients suffering from cardiogenic shock, with no response to conventional therapy, may significantly improve when put on support devices such as extracorporeal membrane oxygenation (ECMO), which maintains systemic and pulmonary circulation, and decongests the heart. This publication presents authors' own experience in qualifying and treating patients with cardiogenic shock, with the use of veno-arterial (VA) ECMO modality. ⋯ VA ECMO is an acceptable therapy for patients in a severe state of cardiogenic shock. In-hospital mortality rate was 59%, and 41% patients (12 subjects) were successfully treated with VA ECMO in course of cardiogenic shock.

Coronary artery disease (CAD) in young adults under 40 years of age is a growing medical, social, psychological and economical problem, related to the prevalence of civilization-related diseases and unhealthy lifestyle. The problem of CAD in young people has not been characterised as well as in older individuals, as the available data mostly come from case reports and small series, often related to genetic aspects and familial occurrence of the disease. ⋯ The population of young patients with CAD is predominantly male, rural, and characterised by a low socio-economic status. The aetiology of CAD in this patient group differs significantly from that in older patients and it is often associated with an unhealthy lifestyle related to rapid civilization changes. The rates of CAD risk factors in young adults are high and the most important risk factors are dyslipidaemia, smoking, and overweight/obesity. Single vessel disease and STEMI presentation were predominant in young patients. Short-term prognosis in young ACS patients is excellent, but long-term prognosis is significantly worse. Further studies on CAD in young adults are warranted, particularly in larger patient populations.

Bicuspid aortic valve (BAV) is strongly associated with aortopathy. Previous studies have suggested that various types of bicuspid aortic valve morphology may differently affect the aortic dilatation. ⋯ Type I BAV cusp fusion morphology is more commonly associated with dilatation of the aorta than type II, especially at the level of the sinus of Valsalva and the ascending aorta.
