Background And Aims: Cervical spondylosis (CS) is reported to be associated with increased sympathetic activity and hypertension. However, the cardiovascular (CV) outcomes of patients with CS are largely unknown.

Methods: A national insurance claims dataset of 22 million enrollees in Taiwan during 1999-2010 was used as the research database. We identified 27,948 patients with CS and age-, sex-, and comorbidity-matched controls. By using multivariate logistic regression analysis after adjustment for potential cardiovascular (CV) confounders, we calculated odds ratios (ORs) with 95% confidence intervals (CIs) to quantify the association between CS and acute coronary syndrome (ACS).

Results: A total of 744 ACS events were identified among the 27,948 patients with CS. The overall incidence of ACS was 4.27 per 1000 person-years in the CS cohort and 3.90 per 1000 person-years in the non-CS cohort, with an adjusted hazard ratio (aHR) of 1.13 (95% CI = 1.08-1.18). The aHRs of ACS were 1.08 (95% CI = 1.03-1.15) in the CS cohort without myelopathy and 1.20 (95% CI = 1.13-1.28) in the CS cohort with myelopathy, compared with the non-CS cohort. Compared with patients with CS without neurological signs, patients with CS receiving rehabilitation exhibited a 0.67 aHRs of ACS (95% CI = 0.59-0.76), whereas those with neurological signs receiving spinal decompression exhibited 0.73 aHRs of ACS (95% CI = 0.63-0.84).

Conclusions: CS is associated with an increased risk of ACS. Receiving treatment for CS, either rehabilitation or spinal decompression, is associated with less risk of ACS.

Article Synopsis
  • A meta-analysis was conducted to evaluate the long-term risks of transient new-onset atrial fibrillation (AF) in patients who experienced acute coronary syndrome (ACS), finding a significant association with adverse outcomes.
  • The study included seven observational studies with over 151,700 patients, showing that transient new-onset AF notably increased the risk of ischemic stroke, recurrent AF, and all-cause mortality, with hazard ratios indicating substantial risks for these conditions.
  • The findings suggest that patients with transient new-onset AF following ACS may benefit from closer monitoring and the potential use of oral anticoagulants to mitigate risks, highlighting the need for further randomized controlled trials.

Aims: This study aimed to evaluate and compare the effectiveness and safety between clopidogrel and ticagrelor in acute coronary syndrome (ACS) with renal dysfunction.

Methods: We conducted a retrospective cohort study on patients on chronic dialysis and whose admission diagnosis between 1 July 2013 and 31 December 2016 included ACS. The primary effectiveness endpoint was a major adverse cardiovascular event (MACE), and the primary safety endpoint was a major bleeding event.

The effects of long-term disturbance of the mineral metabolism on patients with chronic kidney disease (CKD) are unclear. We investigated whether the longitudinal Ca-P (joint calcium and phosphorus) trajectories are associated with incident end-stage renal disease (ESRD), acute coronary syndrome (ACS), and all-cause mortality in patients with CKD. We conducted a prospective cohort study by using data from a 13-year multidisciplinary pre-ESRD care registry.

The aim of this study was to study temporal changes in metabolite profiles in patients with post-acute coronary syndrome (ACS), in particular prior to the development of recurrent ACS (reACS). BIOMArCS (BIOMarker study to identify the Acute risk of a Coronary Syndrome) is a prospective study including patients admitted for ACS, who underwent high-frequency blood sampling during 1-year follow-up. Within BIOMArCS, we performed a nested case-cohort analysis of 158 patients (28 cases of reACS).

Background: Barriers to healthcare are common in the USA and may result in worse outcomes among hospital survivors of an acute coronary syndrome (ACS).

Objective: To examine the relationship between barriers to healthcare and 2-year mortality after hospital discharge for an ACS.

Design: Longitudinal study.
