Environmental Issue and CVD 1
Environmental Issues and Cardiovascular Disease (CVD)
There are many effects of environmental issues on human health. The human health is
directly related with the environment or their natural surroundings. However, one of the major
risks that arises due to environmental issues for human health is cardiovascular disease or CVD.
The heavy air pollution, deforestation in the urban and rural areas, and high rare of emission in
the environment are some of the major environmental causes that cause CVD in people. This is
not only limited to Australian people rather almost half of the world population in almost every
country of the world is suffering with same health issue. The present work explains various
affects of environmental issues on human health and how people are suffering from CVD
because of environmental pollution and high emission of CO2 in the environment.
Cardiovascular (CVD) is most common type of health issue that is responsible for large
number of deaths in all over the world. Cardiovascular disease is related with human heart where
heart of human stops its working and causes death of people. CVD is a group of heart disorder in
which blood vessels not supplied to the heart. Generally cardiovascular disease is known as heart
attack or strokes but there are variety of CVD disease (Anand, Hawkes, De Souza, Mente,
Dehghan, Nugent, & Kromhout, 2015). The common types of CVD are coronary heart disease,
heart attack, heart failure, angina, asthma, cerebrovascular disease, peripheral arterial disease,
congenital heart disease, pulmonary embolism etc. These are acute events and these diseases are
mainly caused by a blockage that prevents blood flow to the heart or to the brain of human-
being. The common symptoms of CVD are chest pain, issue in breathing, pain in left shoulder,
arms, jaw, back or elbows etc. According to a research more than 4.2 million Australian adults
(18.3%) were died from the CVD. Among them 1.2 million of people were died only from heart
attack and strokes (Feigin & Norrving, 2014). Apart from this, more than 2.6 million people are
reported hypertension (high blood pressure) and 430,000 people has faced that they experienced
heart attack at one point of time in their life. It is really threatening for the people who lives in
Australia. CVD is a leading cause of death in the country. According to a research, more than
45,000 (approximately 29%) people died from cardiovascular disease. WHO estimated that air
pollution is responsible for taking more than 7 million premature death globally each year.
However, most of these death numbers can be found in Asian countries like India and China

where pollution is on its highest level (Afshin, Penalvo, Del Gobbo, Kashaf, Micha, Morrish, &
Mozaffarian, 2015).
There are large number of factors behind CVD such as diet of people, poor working
schedule, lack of exercise, high cholesterol level, smoking, drinking, and high blood pressure etc.
but the environmental factor especially air pollution is the major cause of CVD in Australia
(Donovan, Michael, Gatziolis, Prestemon, & Whitsel, 2015). In various recent studies about the
CVD epidemiology, it has been found that the effect of environmental issue can majorly affect
the heart functioning of people. The environmental factors are very much responsible for CVD
such as air pollution, tobacco smokes, and noise exposure in the environment directly related
with the human health and with heart functioning. Furthermore, there are also environmental
issues such as high temperature and heavy rainfall that causes polyaromatic hydrocarbons and
meteorological factors (temperature) are some of the major causes of CVD in human health
(Brumby, Chandrasekara, McCoombe, Kremer, & Lewandowski, 2012). However, Australia’s
greatest health issues is related with high temperature and pollution in urban cities. The mortality
rates due to environmental pollution and heavy emission rate is increasing every day in the
country. In 2014, more than 17 million died from CVD in all over the world and there is a direct
relationship with air pollution and heart related issues in Australia. The lead poisoning and air
pollution are the major environmental issue that causes CVD in people (Mendis, 2017). Apart
from this, all rivers and lakes are contaminated with synthetic chemicals and pesticides that
directly polluted the water (Ali & Qazi, 2012). Water pollution is directly affecting the health of
people because it attacks on the lungs of people and affect the heart as well. Chemicals and
pesticides such as lindane, DDT, or chlordane etc. some of the poisonous chemicals that affect
the human health and causes CVD in the people. As people are continuously using chemicals and
pesticides for large growing agriculture products and fulfill the needs of increasing population, it
is noticeable that these pesticides not only affect the water rather it further affects the functioning
of heart when people consume these pesticides product and chemical water (Laslett, Alagona,
Clark, Drozda, Saldivar, Wilson, & Hart, 2012).
CVD is a major health related burden on Australian people and most of its type is
occurring because of air pollution and low oxygen level in the environment. The deforestation
and excessive use of vehicles in urban areas two major issues that affect the environment in the
