IntroductionAn increasing number of people who have a history of acute coronary syndrome or cerebrovascular accident (termed cardiovascular events) are being considered for surgery. Up-to-date evidence of the impact of these prior events is needed to inform person-centred decision making. While perioperative risk for major adverse cardiac events immediately after a cardiovascular event is known to be elevated, the duration of time after the event for which the perioperative risk is increased is not clear.Methods and analysisThis is an individual patient-level database linkage study of all patients in England with at least one operation between 2007 and 2017 in the Hospital Episode Statistics Admitted Patient Care database. Data will be linked to mortality data from the Office for National Statistics up to 2018, for 30-day, 90-day and 1-year mortality and to the Myocardial Ischaemia National Audit Project, a UK registry of acute coronary syndromes. The primary outcome will be the association between time from cardiovascular event to index surgery and 30-day all-cause mortality. Additional associations we will report are all unplanned readmissions, prolonged length of stay, 30-day hospital free survival and incidence of new cardiovascular events within one postoperative year. Important subgroups will be surgery specific (invasiveness, urgency and subspecialty), type of acute coronary syndrome (ST or non-ST elevation myocardial infarction) and type of cerebrovascular accident (ischaemic or haemorrhagic stroke).Ethics and disseminationEthical approval for this observational study has been obtained from East Midlands—Nottingham 1 Research Ethics Committee; REC reference: 18/EM0403. The results of the study will be made available through peer-reviewed publications and via the Health Services Research Centre of the Royal College of Anaesthetists, London.

Abstract BACKGROUND There are conflicting data on whether changes in N-terminal pro–B-type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) concentrations between time points (delta NT-proBNP and hs-CRP) are associated with a change in prognosis. METHODS We measured NT-proBNP and hs-CRP at 3 time points in 1665 patients with non–ST-segment elevation acute coronary syndrome (NSTEACS). Cox proportional hazards was applied to the delta between temporal measurements to determine the continuous association with cardiovascular events. Effect estimates for delta NT-proBNP and hs-CRP are presented per 40% increase as the basic unit of temporal change. RESULTS Median NT-proBNP was 370.0 (25th, 75th percentiles, 130.0, 996.0), 340.0 (135.0, 875.0), and 267.0 (111.0, 684.0) ng/L; and median hs-CRP was 4.6 (1.7, 13.1), 1.9 (0.8, 4.5), and 1.8 (0.8, 4.4) mg/L at baseline, 30 days, and 6 months, respectively. The deltas between baseline and 6 months were the most prognostically informative. Every +40% increase of delta NT-proBNP (baseline to 6 months) was associated with a 14% greater risk of cardiovascular death (adjusted hazard ratio (HR) 1.14, 95% CI, 1.03–1.27) and with a 14% greater risk of all-cause death (adjusted HR 1.14, 95% CI, 1.04–1.26), while every +40% increase of delta hs-CRP (baseline to 6 months) was associated with a 9% greater risk of the composite end point (adjusted HR 1.09, 95% CI, 1.02–1.17) and a 10% greater risk of myocardial infarction (adjusted HR 1.10, 95%, CI 1.00–1.20). CONCLUSIONS Temporal changes in NT-proBNP and hs-CRP are quantitatively associated with future cardiovascular events, supporting their role in dynamic risk stratification of NSTEACS.

Acute coronary syndrome (ACS) and its complications is one of the main reasons of mortality and invalidation in the world. New biomarkers, such as ST2, NT-proBNP и Pentraxin-3 (Ptx-3) present much more opportunities in the diagnostics of diseases and risk of its development.Aim.To investigate standards and “new” biomarkers in different variants of MI and cardiovascular events in 1 year after MI.Material and methods.In 180 patients with MI (61,4±1,7 years) we determined the serum concentration of standard and “new” (ST2, NT-proBNP, Ptx-3) biomarkers in groups with Q/non-Q, STEMI and NSTEMI and the endpoints (MI, strokes, repeated hospitalizations and sudden deaths) in 1 year (384,3±21,2 days) after MI.Results.Patients with Q-MI and STEMI had higher risk of unfavorable cardiovascular events (p<0,05). Ptx-3 >43,9 ng/ml was shown to be risk factor for sudden death (sensitivity 70,0%, specificity 52,9%), and >125,9±0,06 ng/ml (74,1% and 44,1%) — of recurrent MI.Conclusion.NT-proBNP, ST2 and Ptx-3 showed prognostic value in the diagnostics of unfavorable cardiovascular endpoints.

Aim. To study the influence of hypoglycemic therapy on hospital and long-term prognosis in patients with acute coronary syndrome (ACS) and diabetes type 2.Methods. The study included 63 patients with ACS and type 2 diabetes. All patients had a clinical examination, assessment of mortality risk and myocardial infarction on GRACE scale (Global Registry of Acute Coronary Events) and TIMI (Thrombolisis In Myocardial Infarction) in-hospital and six months after hospitalization.Results. Metformin is associated with a lower estimated risk of in-hospital mortality and within 6 months after discharge in patients with acute coronary syndrome on the background of type 2 diabetes and with less risk of adverse cardiovascular events within 14 days of their occurrence in patients with unstable angina pectoris on the background of diabetes. High daily doses of metformin have also been associated with a decrease in the estimated risk of in-hospital mortality and within 6 months after discharge in patients with ACS associated with diabetes. The inverse association between the daily dosage of metformin and the presence of angina pectoris in patients with ACS and diabetes type 2 indicates a protective effect of metformin high daily dosages in relation to the risk of complications within six months after the discharge from hospital.Conclusion. One of the important aspects of ACS treatment, along with effective therapy, is the impact on concomitant risk factors, including blood glucose control. The main groups of hypoglycemic drugs have currently been identified; their effect on cardiovascular events, long-term effects and long-term prognosis are being investigated.

The present work is devoted to the analysis of modern publications on various aspects of the development and course of ischemic stroke in the presence of acute myocardial infarction. A literature search was conducted on the websites of cardiological and neurological societies, as well as on the PubMed, EMBASE, eLibrary databases using the keywords: myocardial infarction, acute coronary syndrome, stroke, acute cerebrovascular accident, myocardial infarction, acute coronary syndrome, stroke. The authors of this review found that although stroke is a relatively rare complication of myocardial infarction, its prevention is an extremely significant task, since it is associated with high mortality, disability and a significant increase in the cost of treatment. So, it is extremely important to detect thrombosis of the left ventricular cavity in a timely manner, to register preexisting atrial fibrillation that occurs earlier or for the first time, followed by the appointment of anticoagulant therapy. Timely reperfusion treatment, the use of statins and modern dual antithrombotic therapy can reduce the risk of developing cerebrovascular accident in patients with myocardial infarction. It is likely that a decrease in the activity of subclinical inflammation after myocardial infarction will also reduce the risk of stroke, as was recently shown in the COLCOT study. Currently, it remains relevant to search for new knowledge about the risk factors for stroke, which complicated the course of myocardial infarction, which will allow developing more effective and personalized preventive measures in a patient with acute coronary syndrome.
