Introduction: Operative mortality in an acute post-myocardial infarction (AMI) ventricular septal rupture (VSR) is high. In addition to ventricular dysfunction, friable myocardium adds to the technical difficulty of the operation. In a modified infarct exclusion technique, the right ventricle is left undisturbed and the free edge of the pericardial patch is incorporated in the sutures while closing the left ventriculotomy. This simplifies the procedure and decreases the chances of right ventricular dysfunction, any residual defect, and bleeding.
Study Design: A retrospective analysis of patients with VSR following AMI operated in our institute from January 2018 to June 2021 was done.
Results: Over the last 3 years, 16 patients with AMI VSR were treated with a modified infarct exclusion technique. Eight patients presented in cardiogenic shock preoperatively and were put on intra-aortic balloon pump support. All patients could be weaned successfully from the cardiopulmonary bypass, no patient had any residual defect, and none of the patients required re-exploration for bleeding. Postoperatively, 5 patients died within the first week and 2 more patients subsequently died due to intractable arrhythmias over the next 30 days.
Conclusions: In our centre, the mortality following repair of VSR after AMI was 43%. The modified infarct exclusion technique is a good technique with less chances of postoperative re-exploration and residual defect.

Objective: To evaluate the therapeutic effects of Kuanxiong Aerosol (KXA) on ischemic stroke with reperfusion and elucidate the underlying pharmacological mechanisms.
Methods: In vivo pharmacological effects on ischemic stroke with reperfusion was evaluated using the transient middle cerebral artery occlusion (t-MCAO) mice model. To evaluate short-term outcome, 30 mice were randomly divided into vehicle group (n=15) and KXA group (n=15).
Prognostic value of biomarkers of ischaemia in patients with peripheral arterial disease following endovascular revascularisation.

Our aim was to evaluate the prognostic value of detectable high-sensitivity cardiac troponin I (hs-cTnI) and ischaemia-modified albumin (IMA) in predicting all-cause death or non-fatal ischaemic events in patients with PAD after endovascular revascularisation of the lower limbs. Patients who underwent successful endovascular revascularisation for chronic limb-threatening ischaemia (CLTI) or disabling intermittent claudication (IC) were prospectively included. Pre-procedural levels of hs-cTnI and IMA were measured, and patients were followed for one year for the occurrence of the composite outcome of all-cause death, non-fatal myocardial infarction, new-onset angina, non-fatal ischaemic stroke, transient ischaemic attack, or progression of PAD.

Background: Baseline values and the change of platelet count (PLT) during disease were reported to be associated with prognosis of patients with cancer and intensive care treatment. We aimed to evaluate the association between PLT with the course and prognosis of aneurysmal subarachnoid hemorrhage (SAH).
Methods: Admission (AdmPLT) and the 14-days mean PLT (MeanPLT) values of 763 SAH patients treated between 01/2005 and 06/2016 were recorded and, for further analysis, divided into four categories: <150, 150-260, 261-400 and > 400 × 10/L.
Evaluating the effect of noise reduction strategies in CT perfusion imaging for predicting infarct core with deep learning.

This study evaluates the efficacy of deep learning models in identifying infarct tissue on computed tomography perfusion (CTP) scans from patients with acute ischemic stroke due to large vessel occlusion, specifically addressing the potential influence of varying noise reduction techniques implemented by different vendors. We analyzed CTP scans from 60 patients who underwent mechanical thrombectomy achieving a modified thrombolysis in cerebral infarction (mTICI) score of 2c or 3, ensuring minimal changes in the infarct core between the initial CTP and follow-up MR imaging. Noise reduction techniques, including principal component analysis (PCA), wavelet, non-local means (NLM), and a no denoising approach, were employed to create hemodynamic parameter maps.

Objective: To evaluate the relationship between infarct pattern, inferred stroke mechanism and risk of recurrence in patients with ischaemic stroke. The question is clinically relevant to optimise secondary stroke prevention investigations and treatment.
Design: We conducted a retrospective analysis of the dabigatran treatment of acute stroke II (DATAS II) trial (ClinicalTrials.
