Article Synopsis
- - Pyometra is an accumulation of pus in the uterus, and its spontaneous perforation is a rare but serious complication that mimics other acute abdominal issues.
- - A case study of a 90-year-old woman revealed a spontaneous perforation of pyometra, leading to peritonitis; imaging showed fluid and air in the abdomen, necessitating emergency surgery.
- - The woman successfully underwent a hysterectomy with no postoperative complications, highlighting the need for emergency physicians to recognize ruptured pyometra in elderly female patients presenting with acute abdominal symptoms.
Impact of sirolimus-eluting stent fracture on 4-year clinical outcomes.

Background: Although stent fracture (SF) after sirolimus-eluting stent (SES) implantation has been recognized as one of the predisposing factors of in-stent restenosis, it remains uncertain whether SF can increase the risk of major adverse cardiac events (MACE), especially beyond 1 year after SES implantation. The aim of this study was to assess the impact of SF relative to non-SF on 4-year clinical outcomes after treatment with SES of comparable unselected lesions.
Methods And Results: A total of 874 lesions in 793 patients undergoing SES implantation and subsequent angiography 6 to 9 months after index procedure were analyzed.
Aims: To evaluate the frequency, predictors and prognostic significance of elevation in cardiac troponin I (cTnI) after coronary angiography (CAG).
Methods And Results: A series of 296 consecutive patients with normal pre-procedural cTnI levels and undergoing elective CAG at our centre were prospectively analysed. Positive cTnI elevation was defined as >0.
Background: The presence of chronic kidney disease (CKD) is associated with an increased risk of restenosis and major adverse cardiac events (MACEs) after coronary interventions, especially in patients on hemodialysis (HD). The aim of this study was to assess the impact of varying degrees of renal impairment on angiographic and 2-year clinical outcomes after treatment with sirolimus-eluting stents (SESs).
Methods: A total of 675 lesions of 593 patients treated with SES were analyzed.
Background: Although measurement of serum creatine kinase levels, as well as myoglobin levels, has been used for screening patients with acute coronary syndrome (ACS), the specificity of both is low. Measurement of cardiac troponin levels is now extensively used for the diagnosis of ACS because of their superior cardiac specificity. However, troponin levels are reportedly elevated not only in patients with ACS but also in those with other diseases.

However, the relationship between myocardial ischemia and reduced LV distensibility in HCM remains unclear. We aimed to clarify the relationship between exercise-induced ischemia and reduced LV distensibility in patients with HCM.

The effects of nicorandil on left ventricular end-diastolic pressure during exercise were examined in patients with this condition.
Methods And Results: Left ventricular pressures and dimensions were measured simultaneously during supine bicycle exercise in 23 patients with nonobstructive hypertrophic cardiomyopathy, before and after intravenous injection of either nicorandil (0.
