A study of 76 patients with ischemic heart disease is presented who revealed during coronography stenosis of one-three coronary arteries equalling 50-75% of the vessel lumen. Analysis of the effect of anaprilin and nonachlazin on the clinical course and hemodynamics revealed that in patients with initial coronary atherosclerosis of middle age beta-adrenodependent vasodilation of the coronary arteries decreased. In these patients anaprilin may increase the frequency of attacks of spontaneous stenocardia. On the contrary, nonachlazin reduces manifestations of stenocardia but it may be used only in patients with a high tolerance to physical load.

Inflammatory responses and lipid metabolism disorders are key components in the development of coronary artery disease and contribute to no-reflow after coronary intervention. This study aimed to investigate the association between the neutrophil to high-density lipoprotein ratio (NHR) and no-reflow phenomenon in ST-segment elevation myocardial infarction (STEMI) patients after primary percutaneous coronary intervention (PPCI). This study enrolled 288 patients with STEMI from September 1st, 2022 to February 29th, 2024, in the Zhengzhou Central Hospital Affiliated to Zhengzhou University.

Objective: The pathophysiology of delayed cerebral ischemia (DCI) is not fully elucidated. The lack of accurate diagnostic tools increases the probability of delayed diagnosis and timely treatment. The authors assessed the relationship of 8-iso-prostaglandin F2α (F2-IsoP) and oxidative stress biomarkers, nitric oxide synthase 3 (NOS3) and nicotinamide adenine dinucleotide phosphate (NADPH), with DCI after aneurysmal subarachnoid hemorrhage (aSAH).

Background: Ischemic heart disease (IHD) has a significant impact on public health and healthcare expenditures in the United States (US).
Methods: We used data from the CDC WONDER database from 1999-2020 to identify trends in the IHD-related mortality of patients ≥ 75 years in the US. AAMRs per 100,000 population and APC were calculated and categorized by year, sex, race, and geographic divisions.

Occlusion of the distal internal carotid artery can simulate a proximal occlusion of its cervical tract on CT angiography in patients with acute ischemic stroke, that is, pseudo-occlusion. As true and false carotid occlusions can present similarly on non-invasive imaging in patients undergoing endovascular treatment for stroke, our study aimed to evaluate clinical and technical differences of these conditions and the possible consequences of a misdiagnosis. We retrospectively reviewed consecutive patients who underwent mechanical thrombectomy for acute ischemic stroke at a single center between July 2015 and May 2022 and included patients with absent opacification of the cervical carotid artery on CT-angiography.

Ischemic stroke is the most common cerebrovascular disease and the leading cause of permanent disability worldwide. Recent studies have shown that stroke development and prognosis are closely related to abnormal tryptophan metabolism. Here, significant downregulation of 3-hydroxy-kynurenamine (3-HKA) in stroke patients and animal models is identified.
