Background: Consuming opioid agonists is a risk factor for cardiovascular disease particularly in intravenous heroin users. The monthly injectable extended-release opioid antagonist, naltrexone (XR-NTX) is an effective treatment for opioid use disorder. The impact of opioid receptor blockade through XR-NTX on blood pressure, a critical risk factor for cardiovascular morbidity, has not yet been characterized.

Article Synopsis
  • Many patients with coronary artery disease struggle to reach recommended LDL cholesterol levels, but cardiac rehabilitation (CR) programs can help improve adherence to treatments.
  • A study tracked 1,015 patients at different stages of their medical care and found that LDL levels improved from 57% to 63% below 70 mg/dL after 3 months in the CR program, despite high doses of statins being widely prescribed.
  • The findings highlight a treatment gap where many patients still do not meet lipid goals, suggesting a need for stronger lipid-lowering therapies and better adherence to treatment regimens.

Background: Type 2 Diabetes is a major risk factor for cardiovascular (CV) mortality. Insulin resistance can be evaluated non-invasively by insulin sensitivity indices (ISI) such as the Mcauley index (MCAi), which is a function of the fasting insulin and triglycerides. Currently, the association between ISIs and ECG findings and all-cause and CV mortality is still not established in a large scale and heterogeneous population.

Background: Peritoneal dialysis (PD) is increasingly used for the long-term management of hypervolemic refractory congestive heart failure (CHF) patients, in particular when complicated by renal insufficiency. While PD has many advantages over hemodialysis (HD) in those patients, there is a controversy concerning survival superiority of PD compared with HD in this population. The aim of the study was to define typical patient profile and to compare outcomes of patients with CHF and renal failure treated with HD or PD.

Metabolic hormones stabilize brain reward and motivational circuits, whereas excessive opioid consumption counteracts this effect and may impair metabolic function. Here we addressed the role of metabolic processes in the course of the agonist medication-assisted treatment for opioid use disorder (OUD) with buprenorphine or methadone. Plasma lipids, hemoglobin A1C, body composition, the oral glucose tolerance test (oGTT) and the Sweet Taste Test (STT) were measured in buprenorphine- (n = 26) or methadone (n = 32)- treated subjects with OUD.

Article Synopsis
  • Prolonged QTc intervals, often thought to be caused by medications, may actually reflect within-individual variability, which is not well documented.
  • A study examined QTc variations in 188 subjects over time, finding that Bazett's correction method indicated higher QTc values and significant prolonged intervals in some patients compared to other formulas.
  • Clinicians should consider this variability when determining whether to alter a patient's medication, as changes based solely on one measurement might be misleading.

Background: About half of all patients with heart failure are diagnosed with heart failure preserved ejection fraction (HFpEF). Until now, studies have failed to show that medical treatment improves the prognosis of patients with HFpEF.

Objectives: To evaluate changes in exercise capacity of patients with HFpEF compared to those with heart failure with reduced ejection fraction (HFrEF) following an exercise training program.

Introduction There are limited contemporary data regarding the association between improvement in cardiovascular fitness in heart failure patients who participate in a cardiac rehabilitation programme and the risk of subsequent hospitalisations. Methods The study population comprised 421 patients with heart failure who participated in our cardiac rehabilitation programme between the years 2009 and 2016. All were evaluated by a standard exercise stress test before initiation, and underwent a second exercise stress test on completion of 3 ± 1 months of training.

Article Synopsis
  • Elevated levels of high sensitive cardiac troponin (hs-cTnT) are frequently found in asymptomatic elderly individuals, even without acute myocardial infarction, raising questions about their prognostic significance.
  • A study involving nursing home residents showed that their hs-cTnT levels were significantly higher than those of younger healthy volunteers, with a specific cutoff identified for mortality risk evaluation.
  • The research concluded that mild elevations in hs-cTnT are common in the elderly and serve as an independent predictor of one-year mortality, suggesting a need for adjusted cutoff levels for older adults.

Background: Limited information exists on whether changes in medical practices over the study decades have affected the outcomes of acute coronary syndrome (ACS) patients who undergo early coronary artery bypass surgery (CABG) during index hospitalisation.

Methods: Data on trends for early CABG referral and associated outcomes were obtained among 11,485 ACS patients enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) 2000-2010.

Results: Among 11,485 patients, 566 (5%) were referred to early CABG.

The present study was designed to assess the role of jugular venous distension (JVD) as a predictor of short- and long-term mortality in a "real-life" setting. The independent association between the presence of admission JVD and the 30-day, 1- and 10-year mortality was assessed among 2,212 patients hospitalized with acute heart failure (HF) who were enrolled in the Heart Failure Survey in Israel (2003). Independent predictors of JVD finding in study patients included: the presence of significant hyponatremia (odds ratio [OR] 1.

Background: Patients with renal dysfunction (RD) who present with acute myocardial infarction (AMI) are at a high risk for subsequent cardiovascular morbidity and mortality. We sought to evaluate changes in the short and long term mortality of AMI patients with RD compared to patients with normal renal function over the last decade.

Methods: This study based on 4 bi-annually surveys was performed from 2002 to 2010 and included 9468 AMI patients, that were followed for 1year, of whom 2770 (29%) had reduced estimated GFR ([eGFR]<60ml/min/m(2)).

Objective: The Killip classification and the Thrombolysis in Myocardial Infarction (TIMI) score have been proven to be useful tools for the early risk stratification of patients with acute myocardial infarction (MI). The Killip classification is simpler and less time consuming compared to the TIMI score. We sought to evaluate the added value of applying the TIMI score to patients prestratified with the Killip classification.

Giant precordial T wave inversion (GPTI) on ECG may be the result of several pathologies, including myocardial ischemia, pulmonary edema, pulmonary embolism, subarachnoid hemorrhage, apical hypertrophy, and postpacing. We describe a case of a 75-year-old woman who developed GPTI after an episode of gastroenteritis. To our knowledge, this is the first report of this ECG pattern associated with gastroenteritis.

Background: Myocardial infarction (MI) may be classified as ST-elevation MI (STEMI) or non-ST-elevation MI (NSTEMI). There is little data regarding the relationship between the infarct related artery (IRA), clinical characteristics of the patients, and the ST deviation pattern (ie, STEMI or NSTEMI).

Hypothesis: There is a predilection of any coronary artery to a particular ST deviation pattern of acute MI.
