Special Issue Information

Dear Colleagues,

Despite continuous progress in its screening and therapeutic approaches, coronary artery disease (CAD) still emerges as the leading cause for the development and progression of heart failure (HF). The classic integrative strategy of these pathologies focuses on the use of multiple diagnostic tools: clinical, imaging, and biological, followed by both pharmacological and invasive guideline-directed therapeutic management.

Additionally, the complex interplay between CAD and HF is also mirrored by the increasing number of patients presenting with myocardial ischemia and necrosis, but without angiographically significant coronary lesions. In these patients, the pathogenesis as well as the diagnostic and therapeutic approaches are different from CAD with obstructive coronary arteries; therefore, the use of novel techniques (intracoronary imaging, invasive hemodynamic assessment, or cardiac multimodality imaging) is of paramount importance for a timely diagnosis and targeted treatment. Therefore, in this Special Issue, we aim to depict various pathophysiological, clinical, biological, and therapeutical aspects of both obstructive CAD and myocardial infarction with nonobstructive coronary arteries (MINOCA).

A topic of particular interest in this Special Issue is represented by cardiac biomarkers as an integral part of the diagnostic algorithm in CAD. Various classic or novel molecules may provide an objective insight into the pathophysiological imbalances induced by myocardial ischemia, devoid of the subjectivity of patient symptoms, or the often equivocal and operator-dependent imaging aspects.

We aim to update the information on the challenging approach for patients with HF due to CAD; therefore, we welcome all submissions (original research articles or reviews) related to this topic, with a special focus on novel or innovative diagnostic or therapeutic instruments.

Background and Objectives: Chronic heart failure (CHF) caused by ischemic heart disease (IHD) is the leading cause of death worldwide and presents significant health challenges. Effective management of IHD requires prevention, early detection, and treatment to improve patient outcomes. This study aims to expand the diagnostic utility of various 24 h Holter ECG parameters, such as T-wave alternans (TWA), late ventricular potentials (LVPs), and heart rate variability (HRV) in patients with CHF caused by IHD. Additionally, we seek to explore the association between these parameters and other comorbid conditions affecting the prognosis of CHF patients. Materials and Methods: We conducted a prospective case–control study with 150 patients divided into two subgroups: 100 patients with CHF caused by IHD, and 50 patients in the control group. Data included medical history, physical examination, laboratory tests, echocardiography, and 24 h Holter monitoring. Results: Our comparative analysis demonstrated that both TWA and LVPs were significantly higher in patients with CHF compared to the control group (p < 0.01), indicating increased myocardial electrical vulnerability in CHF patients. Both time and frequency-domain HRV parameters were significantly lower in the CHF group. However, the ratio of NN50 to the total count of NN intervals (PNN50) showed a borderline significance (p = 0.06). While the low-frequency (LF) domain was significantly lower in CHF patients, the high-frequency (HF) domain did not differ significantly between groups. Acceleration and deceleration capacities were also significantly altered in CHF patients. Categorizing CHF patients by left ventricular ejection fraction (LVEF) revealed that the mean of the 5-min normal-to-normal intervals over the complete recording (SDNN Index) was significantly higher in patients with LVEF ≥ 50% compared to those with CHF with reduced EF and CHF with mildly reduced EF (p < 0.001), whereas the other HRV parameters showed no significant differences among the groups. Conclusions: Holter ECG parameters can become a reliable tool in the assessment of patients with CHF. The integration of multiple Holter ECG parameters, such as TWA, LVPs, and HRV, can significantly enhance the diagnostic assessment of CHF caused by IHD. This comprehensive approach allows for a more nuanced understanding of the patient’s condition and potential outcomes. Full article
