A recent American study published in the Journal of Circulation Research has suggested that very fine particles emitted from vehicles triggers an inflammatory response in the arteries which in turn leads to atherosclerosis and an increased risk of heart attacks and strokes.
The five week study involved exposing mice to ultra-fine particles sourced from a Los Angeles freeway. These mice experienced a 55% increase in the formation of atherosclerotic lesions when compared to mice breathing filtered air free of the particles.
“Ultrafine particles may deliver a much higher effective dose of injurious components, compared with larger pollutant particles,” said research leader Dr. Andre Nel who is chief of nano-medicine at UCLA.
Recent scientific evidence has shown that a person’s emotional state can have a significant effect on their likelihood of developing coronary heart disease.
Emotions such as anger, hostility, stress, and happiness all play a role in either reducing or increasing heart disease risk. Researchers believe that in individuals that have none of the traditional risk factors associated with heart disease, emotions may be responsible for as many as 50% of heart attacks.
Studies have linked anger, hostility and depression to heart disease, suggesting individuals who display high levels of the three emotions have higher levels of C-reactive protein (CRP) which leads to narrowing of the arterial walls and an increased risk of heart disease.
The heart is a four chambered, hollow muscle and double acting pump that is located in the chest between the lungs. Heart diseases caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. All these add to the formation of atherosclerosis lesions and eventually arterial blockage.
There are some major types of heart diseases:
1.Type of heart disease affecting heart chambers
Heart failure caused by the heart not pumping as much blood as it should and so the body does not get as much blood and oxygen that it needs. The malfunctioning of the heart chambers are due to damage caused by narrowed or blocked arteries.
