Electrocardiography to evaluate for irregularities in heart rhythm. Chest Radiograph to evaluate for presence of lung congestion or increased heart size. [2] [7] Echocardiography to evaluate heart function. Echocardiography is the preferred choice for diagnosis of heart failure in patients. [1] [2] As well as evaluation of lung function via:
The mechanisms behind allergic asthma—i.e., asthma resulting from an immune response to inhaled allergens—are the best understood of the causal factors. In both people with asthma and people who are free of the disease, inhaled allergens that find their way to the inner airways are ingested by a type of cell known as antigen-presenting ...
The strongest risk factor for developing asthma is a history of atopic disease; [66] with asthma occurring at a much greater rate in those who have either eczema or hay fever. [80] Asthma has been associated with eosinophilic granulomatosis with polyangiitis (formerly known as Churg–Strauss syndrome), an autoimmune disease and vasculitis . [ 81 ]
Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.

Premature ventricular contractions may be associated with underlying heart disease, and certain characteristics are therefore elicited routinely: the presence of signs of heart disease or a known history of heart disease (e.g. previous myocardial infarction), as well as heart disease or sudden cardiac death in close relatives.
Feb. 13—Sweating, nausea, dizziness and unusual fatigue may not sound like typical heart attack symptoms. However, they are common for women and may occur more often when resting or asleep.
This article was reviewed by Craig Primack, MD, FACP, FAAP, FOMA. Zone 2 training is a type of cardio exercise where you use your heart rate as a guide to help you find the right intensity for ...
Furthermore, drugs used to treat asthma (such as inhaled glucocorticoids or leukotriene receptor antagonists) also reduce eNO levels. Clinical trials have looked at whether tailoring asthma therapy based on eNO values is better than conventional care, in which therapy is gauged by symptoms and the results of lung function tests.
