How can you explain the global trend and transitions of cardiovascular disease?
Global Trend of death and ill health have been witnessed over time. Societies are becoming gradually more urban and industrialized, infant mortality dropping, and the main causes of death and disability shifting from nutritional deficiencies and infectious disease to non-communicable diseases such as Cardiovascular, causing in an increase in average life expectancy. Health transition in the initial stage of development, which death from cardiovascular disease accounts for less than 10%, mostly are rheumatic heart disease and cardiomyopathies due to infection and malnutrition. Geographical counties presently facing this transition state include sub-Saharan Africa and rural areas of South America and Asia. Furthermore, the reduction in infectious disease burdens, improved nutrition similarly, deaths attributed to CVD increase to up to 35%, manifesting mostly as hypertension, coronary artery disease and stroke with China and other Asian countries experiencing such transition. Life expectancy continues to improve, unhealthy diets, the prevalence of smoking and sedentary lifestyles become more common in the third stage. Deaths attributed to CVD continue to rise in the fourth stage, primarily manifesting as atherosclerosis, coronary artery disease, and stroke, often at ages younger than 50 years. Countries currently experiencing this stage include urban India, Latin America, and Eastern Europe. 50% of deaths are attributed to CVD in developed countries and usually present as coronary artery disease, stroke or congestive heart failure at more advanced ages. Furthermore, the last stage describes conditions of social confusion causing in a breakdown of the health system in which there is a recovery of diseases with persistence of third and fourth stages.
