Heart Failure

Heart failure can be caused due to many reasons like heart attack, coronary heart disease or high blood pressure. Heart failure occurs when the heart is unable to receive the proper supply of oxygen through blood. It may occur due to narrowing of heart arteries that pump blood to the heart or high blood pressure due to which the heart become weak and is unable to pump blood in a proper way causing heart failure. The common symptoms of the heart failure include shortness of breath, fatigue and irregular rapid heartbeat as the heart is unable to pump the blood properly so the oxygen level decreases in the blood due to which the heart will beat rapidly to meet the oxygen demand hence there is shortness of breath. Heart failure can be chronic or acute. Heart failure can be diagnosed by Electrocardiogram, chest X-ray and blood tests. There is no treatment for the heart failure but symptoms can be controlled that help the person to live longer life. Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
