Ventricular structural changes in patients with sleep-disordered breathing (SDB) and myocardial infarction
2018
Obstructive sleep apnea (OSA) is associated with cardiovascular diseases. Aim: To analyze structural parameters of myocardial damage in patients presenting with acute coronary syndrome (ACS) and its relationship with OSA severity. Method: This is a prospective, observational study in patients with a first acute myocardial infarction (MI) treated by percutaneous coronary intervention (PCI). Cardiovascular magnetic resonance (CMR) studies were performed at 3 days and 6 months. Eligible patients underwent a polysomnography within 30 days after PCI. Quantitative data were expressed as mean±SD. Linear regression analysis was used to describe associations between infarct characteristics and OSA. …
Assessment of no-reflow phenomenon by myocardial blush grade and pulsed wave tissue doppler imaging in patients with acute coronary syndrome
2014
Background: No-reflow phenomenon is a complication of myocardial revascularization and it is associated with a worse prognosis. Materials and Methods: A prospective study was carried out enrolling patients with acute myocardial infarction (64 patients, 49 male and 15 female, median age 64.9 ± 10.61 years), both STEMI and NSTEMI, who underwent myocardial revascularization with percutaneous coronary intervention (PCI). TIMI flow and Myocardial Blush Grade (MBG) were assessed at baseline (T0), in addition to tissue Doppler imaging (TDI) and electrocardiogram. Cardiological evaluation was also performed at T1 (one month after PCI) and T2 (every year after revascularization for a mean follow-up …
Is neural network better than logistic regression in death prediction in patients after ST-segment elevation myocardial infarction?
2021
Background: There is a need to develop patient classification methods to adjust post-discharge care, improving survival after ST-segment elevation myocardial infarction (STEMI). Aims: The study aimed to determine whether a neural network (NN) is better than logistic regression (LR) in mortality prediction in STEMI patients. Material and methods: The study included patients from the Polish Registry of Acute Coronary Syndromes (PL-ACS). Patients with the first anterior STEMI treated with the primary percutaneous coronary intervention (pPCI) of the left anterior descending (LAD) artery between 2009 and 2015 and discharged alive were included in the study. Patients were randomly divided into th…
Low-dose rivaroxaban and aspirin among patients with peripheral artery disease: a meta-analysis of the COMPASS and VOYAGER trials.
2021
Abstract Aims Peripheral artery disease (PAD) patients suffer a high risk of major cardiovascular (CV) events, with athero-thrombo-embolism as the underlying pathophysiologic mechanism. Recently, two large randomized clinical trials evaluated the efficacy and safety of low-dose rivaroxaban twice daily plus aspirin in stable PAD outpatients and those immediately after peripheral revascularization. We sought to determine if the effects of low-dose rivaroxaban and aspirin compared to aspirin alone are consistent across this broad spectrum of PAD patients. Methods and results We conducted a random-effects meta-analysis of the COMPASS and VOYAGER randomized trials among 11 560 PAD patients (4996…
Management of Blood Pressure and Heart Rate in Patients with Acute Stroke
2017
BACKGROUND: Stroke represent one of the most devastating of all neurological diseases, affecting about 15 million people per year and is an important cause of morbidity and mortality worldwide and currently the leading cause of adult disability in developed countries. Blood pressure and heart rate may undergo several modifications in patients with both ischemic and hemorrhagic stroke in fact raised blood pressure levels may lead to cerebral edema, hematoma expansion or hemorrhagic transformation and in contrast low blood pressure can lead to increased cerebral infarction or perihematomal ischemia. In addition, ECG abnormalities and cardiac arrhythmias, especially atrial fibrillation, are re…
Cardiovascular effects of nocturnal aircraft noise on healthy volunteers
2013
Background: Nighttime aircraft noise can impair sleep quality and may also increase blood pressure and the risk for myocardial infarction for persons in highly noise exposed residential areas. Pathophysiology and possible susceptibility factors for cardiovascular effects of aircraft noise remain unclear. Methods and results: 75 healthy volunteers (mean age 26 y) were studied for three nights in their homes. One control pattern without noise (Control) and two noise patterns with 30 (Noise 30) or 60 (Noise 60) aircraft noise events were played back in random and blinded order. After each study night flow-mediated dilatation (FMD) of the brachial artery was measured the following the morning. …
High-Sensitivity Procalcitonin (hs-PCT): A Marker for Identification of Arteriosclerosis and Myocardial Infarction?
2008
Background: Procalcitonin (PCT) is a protein hormone induced by bacterial inflammation that serves as a marker of sepsis. C-reactive protein (CRP) is also known to be a marker of inflammation and, in low concentrations, a prognostic marker for latent or early arteriosclerosis. Arteriosclerosis is considered as an inflammatory process that begins in the wall of an artery. In addition to CRP, the concentration of other markers of inflammation increases in the presence of arteriosclerosis. Methods: To determine if PCT is among these markers, the serum concentration of PCT was quantified in blood samples from healthy individuals (n = 410) and at admission in 774 patients, 92 with peripheral art…
Diabetes Mellitus and Its Impact on Patient-Profile and In-Hospital Outcomes in Peripheral Artery Disease
2021
Background: In patients with peripheral artery disease (PAD), the impact of diabetes mellitus (DM) on patient-profile and adverse in-hospital events is not well investigated. Methods: The German nationwide inpatient sample 2005–2019 was used for this analysis. Hospitalized PAD patients were stratified for DM and the influence of DM on patient-profile and adverse in-hospital events was investigated. Results: Our study comprised 2,654,871 hospitalizations (54.3% aged ≥70 years, 36.7% females) of patients with PAD in Germany 2005–2019. Among these, 864,691 (32.6%) patients had DM and 76,716 (2.9%) died during hospitalization. Diabetic PAD patients revealed an aggravated cardiovascular profile …
COVID ‐19, thromboembolic risk, and Virchow's triad: Lesson from the past
2020
Abstract COronavirus Infectious Disease which started in 2019 (COVID‐19) usually presents with the signs and symptoms of pneumonia. However, a growing number of recent reports highlight the fact that the infection may be by far more than only a respiratory disease. There is evidence of an increased thromboembolic risk in COVID‐19 patients, with a variety of manifestations in terms of ischemic stroke, deep vein thrombosis, acute pulmonary embolism, acute myocardial infarction, systemic arterial embolism, and placental thrombosis. The German physician Rudolph Virchow, about two centuries ago, described three pivotal factors contributing together to thromboembolic risk: endothelial injury, hyp…
