|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.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
