In patients who are considered low risk based on clinical risk scores, right ventricular dysfunction may be present.

A PERT alert requires either a CT diagnosis of PE or a VQ scan showing a high probability of PE, combined with one of three additional criteria: elevated B-type (brain) natriuretic peptide (BNP) and troponin; echocardiographic evidence of right ventricular dysfunction; or clinical instability as indicated by heart rate over 110 beats per minute, systolic blood pressure below 100 mm Hg, or oxygen saturation lower than 90%.
Currently, there is no inexpensive or noninvasive test for detecting asymptomatic left ventricular dysfunction. But researchers from the Mayo Clinic may have solved this problem--by applying AI to an already affordable early indicator of heart disease--the EKG, according to a report from researchers at Mayo Clinic.
For patients with the same diffuse coronary artery disease, many studies have also confirmed that besides myocardial infarction as a risk factor for left ventricular dysfunction, some traditional risk factors for coronary heart disease, such as family history of coronary heart disease, age, smoking, PCI history, stroke history, history of peripheral vascular disease, chronic complete closure, were also confirmed not associated with left ventricular dysfunction, which may be related to the establishment of collateral circulation, ischemic preconditioning, and ischemic postconditioning.10-13 For the elderly patients with CHD excluding MI history, there was no partial loss of myocardial cell mass caused by abrupt closure of the coronary artery.
A common but dangerous sleep disorder, OSA causes an increased risk for left ventricular and, more rarely, right ventricular dysfunction in the heart.
The study found that OSA causes an increased risk for left ventricular and, more rarely, right ventricular dysfunction in the heart, causing cardiac risks.
Additionally, Prexxartan has also been indicated for stable left ventricular failure or left ventricular dysfunction after myocardial infarction.
Release of cytokines such as interleukin (IL)-6 and IL-8 may cause myocardial tissue inflammation and biventricular hypertrophy and dilation with global ventricular dysfunction. Furthermore, studies have suggested that overproduction of IL6 and IL-8 may induce thrombopoiesis, neutrophil migration, and myxoma cell fragment adhesion to coronary artery endothelium, leading to myocardial ischemia and infarction.
Conventional echocardiography is a simple economical test for detecting LV dysfunction in normotensive, asymptomatic and type 2 diabetic patients, and should be applied to detect early Left ventricular dysfunction so that actively preventive and therapeutic treatment could be planned early to prevent long-term morbidity and mortality and LV functions may be preserved for long.
In about 2-4% of cases, bevacizumab causes reversible cardiomyopathy and left ventricular dysfunction even in patients without preexisting cardiac disease [6].
