The effect of cold and/or a raised partial pressure of oxygen was examined in eleven people with no demonstrable cardiac abnormality but who had pulmonary oedema when scuba diving or surface swimming, and in ten normal divers. These stimuli induced pathological vasoconstriction in the pulmonary oedema group, nine of whom also showed signs of cardiac decompensation when so stimulated. The pulmonary oedema patients have been followed-up for an average of 8 years. Seven have become hypertensive. Except for the onset of lone atrial fibrillation in one normotensive female diver and development of Raynaud's phenomenon in a normotensive man, there have been no cardiovascular events and no deaths.

Phosphodiesterase-5 inhibitors (PDE5Is) improve erectile function by enhancing nitric oxide availability in the penis and its supplying vasculature, resulting in vasodilation and increased blood flow. PDE5Is might benefit cardiovascular diseases because phosphodiesterase-5 is also located elsewhere in the body, including the pulmonary and systemic vasculature and in hypertrophied myocardium. PDE5Is are approved for pulmonary arterial hypertension, given that they improved several hemodynamic and clinical parameters in large randomized trials. Initial evidence suggests that PDE5Is benefit patients with congestive heart failure and secondary pulmonary hypertension. PDE5Is seem to improve hemodynamic and clinical parameters in patients with high-altitude pulmonary edema (HAPE) and high-altitude pulmonary hypertension. In climbers with prior episodes of HAPE, PDE5Is prevented HAPE in 2 small randomized trials. In small randomized trials of PDE5Is, patients with Raynaud's phenomenon demonstrated improved blood flow, fewer symptoms and frequency of attacks, and resolution of digital ulcers. In addition to enhancing vasodilation, PDE5Is seem to protect the myocardium through complex pathways that involve nitric oxide, cyclic guanosine monophosphate, protein kinase G, extracellular-signal-regulated kinase, B-cell lymphoma protein-2, and Rho kinase inhibition. In animal models of acute myocardial infarction, PDE5Is consistently reduced infarct size indicating cardioprotection and PDE5Is also promote reverse remodeling and reduce myocardial apoptosis, fibrosis, and hypertrophy. PDE5Is might also benefit patients with treatment-resistant hypertension, preeclampsia, or peripheral arterial disease. This review presents the pathophysiology and trial data with regard to the use of PDE5Is for cardiac diseases.

The effects of phosphodiesterase type 5 inhibitors on vasodilation mediated via nitric oxide-cyclic guanosine monophosphate are well described. Less is known about other mechanisms through which phosphodiesterase type 5 inhibitors benefit endothelial function, including normalization of serum biomarkers, increased levels of endothelial progenitor cells, ischemia-reperfusion protection mechanisms, and other actions specific to patients with diabetes. These various mechanisms are reviewed. Their impact on several cardiovascular diseases, including erectile dysfunction, pulmonary hypertension, heart failure, high-altitude pulmonary edema, Raynaud's phenomenon, coronary artery disease, diabetes, and atherosclerosis, is presented.

A 30-year-old female was symptomatic with headache, fatigue, and weakness since October 2011 and was told to have anemia. In January 2012, she was admitted outside with pulmonary edema. Investigations revealed advanced azotemia, anemia, and hypercalcemia. Urine showed 2 + proteins and 30-35 red blood cells. There was no history of oral ulcers, rash, Raynaud's phenomenon, or hemoptysis. She was evaluated for causes of rapidly progressive "renal failure." Hemolytic work-up; antinuclear antibody, double-stranded DNA, and anti-neutrophil cytoplasmic antibody were negative. Kidney biopsy was done and interpreted as acute interstitial nephritis with hyaline casts. She was started on hemodialysis and treated with steroids and cyclophosphamide. She came to our institute in January 2012. Investigations showed evidence of paraproteinemia with kappa restriction. Bone marrow showed 15% plasma cells. Kidney biopsy was reviewed and was diagnostic of cast nephropathy. She was treated with 6 monthly cycles of dexamethasone and bortezomib. She achieved complete remission in July 2012. Maintenance doses of bortezomib were continued until May 2014. Autologous bone marrow transplantation was performed on June 06, 2014. Monthly, bortezomib was continued till April 2015. Subsequently, workup for renal transplantation was started with her father as her donor. Test for sensitization was negative. Renal transplantation was done on January 1, 2016, with prednisolone, mycophenolate, and tacrolimus. She achieved a serum creatinine of 0.6 mg% on the 4th postoperative day. Thereafter, she continues to remain stable.
