Relationship between dyspnea and chest pain ischemic heart disease

Abstract

Dyspnea may form a differential diagnostic symptom to chest pain in ischemic heart disease (IHD) but may also precede angina pectoris (AP) as a manifestation of IHD. In the Primary Preventive Trial in Göteborg the occurrence of AP and its relation to dyspnea has been studied in a random population sample of men aged 47-54 years at entry to the study and followed for 4 years. In the corss-sectional study dyspnea was reported in 21% of the total population and in 70% of the angina population. Dyspnea at entry to the study was reported in 36% among cases who developed AP along during the follow-up time and in 35% among cases who developed AP associated with myocardial infarction. The dyspnea was not related to smoking habits or to low grade of physical activity. The report of dyspnea before chest pain in IHD may be due to misinterpretation in early cases. On the other hand it is also known that intermittent left ventricular failure coincident with attacks of myocardial ischemia will give a subjective feeling of dyspnea. According to our study there is a definite association between AP and dyspnea. In some cases dyspnea precedes AP whereas in others the chest pain precedes the dyspnea. The symptom dyspnea also carries important pro...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
