Coronary artery disease is the leading cause of acute and chronic heart failure. Patients with heart failure and ischemic heart disease need a tailored assessment to define the appropriate treatment, while a specific multidisciplinary management plan should be followed. Indeed, several factors should be assessed before starting treatment, such as heart failure symptoms and/or signs, angina, electrocardiographic features, right and left ventricular systolic and diastolic function, serological abnormalities, cardiac structural and functional integrity, and pulmonary function. New scenarios and developments have emerged recently in this field, increasing our knowledge regarding pathophysiology, exercise, and pharmacology. Effective and appropriate management and treatment reduce the risk of death and hospitalization for heart failure. Herein, we provide an updated, state-of-the-art overview of pharmacological treatment and cardiac rehabilitation in patients with chronic heart failure and coronary artery disease. Furthermore, tailored and contemporary management in clinical practice will be proposed for this specific and fragile patient population.

High levels of homocysteine (Hcy) have been linked with adverse cardiovascular outcomes, such as arrhythmias and stroke. In the context of paroxysmal atrial fibrillation (PAF), hyperhomocysteinemia has been demonstrated to be an independent predictor of future events. The aim of this report was to address the potential value of Hcy levels in predicting future paroxysms of atrial fibrillation (AF), as well as to identify the potential mechanisms of action. We searched PubMed and the Cochrane Database on 16 January 2022. Keywords used were homocysteine or hyperhomocysteinemia paired with a total of 67 different keywords or phrases that have been implicated with the pathogenesis of AF. We included primary reports of clinical and non-clinical data in the English language, as well as systematic reviews with or without meta-analyses. We placed no time constraints on our search strategy, which yielded 3748 results. Following title review, 3293 reports were excluded and 455 reports were used for title and abstract review, after which 109 reports were finally used for full-text review. Our review indicates that Hcy levels seem to hold a predictive value in PAF. Herein, potential mechanisms of action are presented and special considerations are made for clinically relevant diagnostic procedures that could complement plasma levels in the prediction of future PAF events. Finally, gaps of evidence are identified and considerations for future clinical trial design are presented.

HFpEF represents a heterogeneous syndrome with complex pathophysiological substrates and multiple clinical manifestations. Recently, much attention has been focused on cardiac rehabilitation programs for HFpEF patients, and several studies have examined the effects of exercise training on this specific population. This systematic review and meta-analysis included studies on adult patients with HFpEF and evaluated the impact of exercise on the cardiorespiratory fitness variables measured during CPET. The primary outcome was the difference in the change in the peak oxygen uptake (Δpeak VO₂) between the groups. Literature search involved PubMed/MEDLINE, Cochrane/CENTRAL and Scopus databases. From an initial 5,143 literature records, we identified 18 studies fulfilling the inclusion criteria; 11 studies with 515 patients were finally included in the primary outcome analysis. Δpeak VO₂ between baseline and study end was significantly higher in the groups of exercise training versus control (WMD 2.25 ml/kg/min, 95% CI 1.81-2.70). Exercise training resulted in greater change in the 6-minute walking test (6MWT) distance (WMD 2.25 m, 95% CI 1.81-2.70). Health-related quality of life (HRQoL) (WMD: -3.36, 95% CI -9.42 to 2.70, I² = 14%, p = 0.33) and echocardiographic indices of diastolic function showed no differences between exercise and control groups at study end. In the subgroup analysis, no difference between resistance versus aerobic exercise was noted in Δpeak VO₂, but high-intensity interval training showed a greater increase in peak VO₂ versus aerobic exercise (WMD 1.62 ml/kg/min, 95% CI 0.96-2.29, I² = 0%, p = 0.82). Exercise training in HFpEF results in significant improvements in peak VO₂ and 6MWT distance as compared to those for controls. High-intensity interval training may offer greater enhancement of the exercise capacity of these patients than standard aerobic exercise.

5-Fluorouracil (5-FU) is a widely used chemotherapeutic agent that can cause cardiotoxicity manifesting, among others, as chest pain. Capecitabine is an oral prodrug of 5-FU, with reported preferen...
