Comparative Study
Relationships between paced QRS duration and left cardiac structures and function.
In patients with congestive heart failure, QRS duration (QRSd) is correlated with left ventricular (LV) ejection fraction (LVEF), ventricular dyssynchrony and patients' prognosis. However, little is known about the relationships between paced QRS duration (pQRSd) to cardiac structures and function and ventricular dyssynchrony in patients with chronic right ventricular apical (RVA) pacing, which were investigated in this study. ⋯ pQRSd is correlated with left cardiac structures and LV systolic function. pQRSd > or =180 ms indicates left atrial dilation. There is no correlation between pQRSd and ventricular dyssynchrony.

Comparative Study
Pre-hospital statin therapy may not reduce incidence of all-cause mortality and overall MACCE during hospital stay after coronary artery bypass graft surgery.
The available literature has not been able to demonstrate the exact association between preoperative statin therapy and the reduction in the rates of major adverse cardiac and cerebrovascular events (MACCE). The aim of this study is to explore these unanswered questions. ⋯ Pre-hospital statin therapy did not reduce the risk of mortality or the rates of MACCE during in hospital stay after CABG surgery.

Case Reports
Successful resection of a giant subpericardial lipoma with recurrent ventricular arrhythmias.
We report a case of a giant subpericardial lipoma with ventricular arrhythmias. It was resected through a median sternotomy without cardiopulmonary bypass. The tumour was about 21x23x5 cm and weighed 2100 g. After resection the heart rhythm returned to sinus rhythm.

A causal relationship between migraine and a right-to-left shunt, due to a patent foramen ovale (PFO), has been suggested. In mainly retrospective studies, percutaneous closure of a PFO has been associated with a decrease in the prevalence of migraine. ⋯ Percutaneous PFO closure is related to a decrease in the prevalence of migraine in this prospective observational study. However, randomized placebo controlled trials have to confirm these findings.

Randomized Controlled Trial Comparative Study
Acute normovolaemic haemodilution with crystalloids in coronary artery bypass graft surgery: a preliminary survey of haemostatic markers.
Acute normovolaemic haemodilution (ANH) is a safe and cost-effective blood conservation strategy in procedures with great blood loss. It eliminates the risk of administrative errors and also contaminations that may occur whenever banked blood is used. Classically, haemodilution is regarded as causing coagulopathy. This study was designed to determine the effect of crystalloids on measured coagulation values and perioperative blood loss following ANH in patients undergoing elective coronary revascularization. ⋯ ANH reduced the need for PRBC and FFP by 58% and 74%, respectively. Regarding the increase in PT and decrease in Plt count, we concluded that performing ANH with saline solution (SS) in patients undergoing CABG surgery may cause a non-clinically significant change in coagulation state.
