The risk of developing coronary artery disease is increased up to threefold by
Diabetes mellitus
Hypertension
Obesity
High alcohol consumption
The Correct Answer is A
Coronary artery disease (CAD) is a condition where the arteries that supply blood to the heart become narrowed or blocked due to a buildup of plaque. Several risk factors contribute to the development of CAD, including diabetes mellitus, hypertension, obesity, high alcohol consumption, smoking, and a family history of CAD.
Research suggests that individuals with diabetes mellitus are two to four times more likely to develop CAD than those without diabetes. This is because diabetes can lead to damage to the blood vessels and nerves that control the heart, as well as increased inflammation and high levels of blood glucose that can contribute to the buildup of plaque in the arteries.
While hypertension, obesity, and high alcohol consumption are also known risk factors for CAD, they generally do not increase the risk to the same degree as diabetes. Nonetheless, these factors can contribute to the development and progression of CAD and should be addressed through lifestyle modifications and medical interventions.

Correct Answer is D
Explanation
Sustained hypertension can lead to several complications, including damage to the blood vessels in the retina (retinopathy), increased risk of stroke, and damage to the kidneys (renal disease). Other potential complications include heart disease, peripheral arterial disease, and cognitive impairment. It is important to manage hypertension through lifestyle modifications and medication to prevent these complications.
Correct Answer is C
Explanation
The left ventricle is responsible for pumping oxygenated blood out of the heart and into systemic circulation, which requires generating enough pressure to overcome the resistance of the systemic blood vessels. Therefore, the left ventricle has thicker and more muscular walls than the right ventricle and can generate higher pressures during contraction. In contrast, the right ventricle pumps deoxygenated blood to the lungs, which have lower resistance compared to the systemic circulation, and therefore do not need to generate as high pressures.
