This method for isolating functional immune cells from the heart provides an alternative to the conventional methods of collagenase digestion, which causes unwanted immune cell activation, resulting in a decreased responsiveness of these cells. Our method of isolation yields functional cardiac immune cells by avoiding problems associated with enzymatic digestion.

Langendorff-mode isolated heart perfusion, in conjunction with 31P NMR spectroscopy, combines the fields of biochemistry and physiology into one experiment. The protocol allows for the dynamic measurement of high energy phosphate content and turnover in the heart while concurrently monitoring physiologic function. When performed correctly, this is a valuable technique in the assessment of cardiac energetics.

The aim is to promote a new approach to cardiac rehabilitation (CR), using a unique remote patient monitoring system that will enable healthcare providers to monitor CR patients at home at low cost, with the intention of making CR services more accessible and improving compliance. The study is currently underway.
FAQs
Different measurement modalities capture different stages of cardiac performance. An electrocardiogram records electrical voltage changes, making it useful for examining heart rate and rhythm. Pressure measurements and imaging add information about chamber movement and blood flow. Considering these signals together helps investigators distinguish an electrical abnormality from impaired contraction or altered circulation rather than treating every finding as the same problem.
Exercise, autonomic regulation, and drug exposure can change the cardiac measurements being monitored. Comparing recordings under these biological contexts allows researchers to examine how cardiac performance responds to physiological demand, regulatory influences, or treatment. The resulting patterns can connect heart activity with broader biological processes and help evaluate whether an intervention alters function in a direction relevant to the study.
Electrical activity, contraction, and circulation should be interpreted as related but distinct aspects of function. A rhythm may appear abnormal even when the central question concerns contraction, while chamber movement or blood flow may reveal changes not described by voltage recordings alone. Selecting measurements that match the biological question improves interpretation of cardiovascular physiology and health.
An appropriate monitoring setup depends on the information required. Electrical assessment uses sensors to record voltage changes, whereas pressure-based assessment and imaging address different aspects of cardiac performance. Researchers therefore select the modality, or combination of modalities, that can evaluate heart rate, rhythm, chamber movement, or blood flow for the question under study.
In a biology investigation, measurements can be related to exercise, autonomic regulation, disease, or drug exposure. This makes cardiac function monitoring useful not only for describing cardiovascular physiology but also for comparing cardiac responses across conditions. The same strategy can support physiological research, disease diagnosis, treatment evaluation, and studies aimed at developing therapies that protect or restore heart function.
Results may reveal abnormal rhythms, impaired contraction, or altered circulation, depending on which signals are collected. These findings provide evidence for evaluating cardiovascular health and for assessing how disease or treatment affects the heart. Because each method emphasizes a different feature, interpretation should connect the observed outcome with the measurement type rather than assuming every abnormal result has the same meaning.
