|Cardiomyopathy is a condition in which the heart muscles are unable to contract properly. So because of this the heart is unable to pump the blood to the whole body properly. This condition can lead to heart failure. Cardiomyopathy may be of two type- intrinsic cardiomyopathy and extrinsic cardiomyopathy. In this the heart muscles may become too weak to pump blood to the body or may contract irregularly that can even lead to sudden death. The signs and symptoms are usually similar to other heart problems also and the common signs and symptoms include shortness of breath, swelling of the legs due to accumulation of fluid in the body, cough, weakness and dizziness. The conditions only worsen with time so the disease should be treated at proper time. It can be diagnosed by either chest X-ray or by electrocardiogram. The person with severe problems may even need heart transplant.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
