Background: Coronary air embolism (CAE) is a complication that can lead to catastrophic outcomes, including myocardial infarction, stroke, and death. It is reported to occur during cardiac catheterization, within a few hours after cardiac surgery, or as a result of chest trauma. This is a case report of delayed coronary air embolism following cardiac surgery.
Case Presentation: A 58-year-old female presented with New York Heart Association (NYHA) Class II symptoms resulting from severe, highly eccentric anterior mitral regurgitation from a bio-prosthetic valve. She had preserved ejection function and a total calcium score of zero. This patient underwent a re-do mechanical mitral valve replacement. Two days post-surgery, she was brought to the catheterization laboratory with signs and symptoms suggestive of an inferior myocardial infarction (MI) and complete heart block (CHB). Her symptoms and ST changes resolved immediately after the introduction of angiographic contrast. Angiography revealed no occlusion in the right coronary artery (RCA).

Background: Congenital heart disease (CHD) is a common birth defect. Our previous studies suggest that indoor air pollution, especially total volatile organic compounds (TVOCs), may increase fetal CHD risk, whereas vitamin and folic acid (FA) supplements in early pregnancy might offer protection against CHD. However, limited research has explored whether FA or multivitamin supplementation can mitigate the effects of TVOCs exposure on CHD.

Air-breathing vertebrates face many physiological challenges while breath-hold diving. In particular, they must endure intermittent periods of declining oxygen (O) stores, as well as the need to rapidly replenish depleted O at the surface prior to their next dive. While many species show adaptive increases in the O storage capacity of the blood or muscles, others increase the oxidative capacity of the muscles through changes in mitochondrial arrangement, abundance, or remodeling of key metabolic pathways.

Background: Rheumatic mitral stenosis (RMS) is a common valvular heart disease in developing countries. We sought to evaluate the early experience of patients with RMS undergoing transcatheter mitral valve replacement (TMVR).
Methods: In this retrospective study, a total of 5 RMS patients accepted TMVR.

Background: Spinal cord injury (SCI) often leads to the loss of urinary sensation, making urination difficult. In a previous experiment involving six healthy participants, we measured heartbeat-induced acoustic pulse waves (HAPWs) at the mid-back, calculated time-series power spectra of heart rate gradients at three ultralow/very low frequencies, distinguished and formulated waveform characteristics (one characteristic for each power spectrum, nearly uniform across participants) at times of increased urine in the bladder and heightened urges to urinate, and developed an algorithm with five of these power spectra to identify when urination is needed by extracting the waveform portion (continuous timepoints) where all of the characteristics were consistent with the formulated characteristics. The objective of this study was to verify the validity of the algorithm fed with data from measured HAPW of participants with SCI and to adapt the algorithm for these individuals.

Background: Anemia is a prevalent comorbidity in COPD associated with increased morbidity. However, the significance of longitudinal anemia status and variation in anemia status trends over time in COPD are not known. Furthermore, individuals with COPD and smoking history often have multiple comorbidities, in particular cardiovascular disease.
