AI Article Synopsis
- Myocardial perfusion SPECT is a key tool in diagnosing and managing coronary artery disease (CAD), providing insights into heart function and ischemia, among other conditions.
- It helps assess the severity of CAD by combining functional imaging with anatomical tests, particularly for patients with intermediate risk profiles.
- The review discusses modern practices integrating SPECT imaging with other techniques to enhance diagnostic accuracy and improve patient outcomes in CAD management.
Article Abstract
Myocardial perfusion single photon emission computed tomography (SPECT) is widely used in assessing coronary artery disease (CAD) owing to its proven efficacy in extensive clinical experience. Like other functional tests, myocardial SPECT is recommended for the diagnosis of obstructive CAD, risk stratification assessment, and treatment decision making. Besides quantifying left ventricular volume, global and regional function by electrocardiography (ECG)-gated acquisition, myocardial SPECT can identify myocardial ischemia, scars, stunning, and viable hibernating myocardium. It provides comprehensive functional data across the spectrum of CAD and a cost-effective strategy in patients with intermediate pre-test probability of CAD or with a history of ischemic cardiomyopathy. With ongoing advances in cardiovascular prevention and risk factor management many patients referred for testing now have a low-to-intermediate probability of CAD. Besides, CAD has become a chronic condition resulting from novel therapeutic strategies. Against this background, approaches combining anatomical and functional tests in sequence or simultaneously include coronary artery calcium score integrated with perfusion imaging or fusion SPECT/coronary computed tomography angiography (CCTA). In this review we summarize current indications for myocardial perfusion SPECT and integration of SPECT with other imaging techniques to improve diagnostic performance, patient management, and outcome prediction in CAD.

Focusing on microvascular function in heart failure with preserved ejection fraction.

Heart failure is a prevalent global health issue. Heart failure with preserved ejection fraction (HFpEF), which already represents half of all heart cases worldwide, is projected to further increase, driven by aging populations and rising cardiovascular risk factors. Effective therapies for HFpEF remain limited, particularly due to its pathophysiological heterogeneity and incomplete understanding of underlying pathomechanisms and implications.

Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

As several decades of research have shown the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors alone or in combination with diuretics, we were interested in investigating the effects of subchronic therapy of these drugs on ischemia-reperfusion (I/R) damage to the heart, as well as their influence on oxidative status. The research was conducted on 40 spontaneously hypertensive male Wistar Kyoto rats, divided into 4 groups. Animals were treated for four weeks with 10 mg/kg/day zofenopril alone or in combination with hydrochlorothiazide, indapamide and spironolactone per os.

Background: The majority of functional ischemia tests in patients with suspected chronic coronary syndromes (CCS) yield normal results. Implementing gatekeepers for patient preselection, such as pretest probability (PTP) and/or coronary artery calcium score (CACS), could reduce the number of normal scan results, radiation exposure and costs. However, the efficacy and safety of these approaches remain unclear.

Purpose: Research on the safety and efficacy of del Nido cardioplegia in adult patients with reduced left ventricular ejection fraction (LVEF) is limited. We evaluated the effect of del Nido cardioplegia on early outcomes of cardiac surgery in this cohort.
Methods: PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched through August 2024 to conduct a meta-analysis comparing del Nido to other cardioplegia in adult patients with reduced LVEF (≤50%).
