Answer 1

Ans) 15) A) Stroke

Explaination:

- Sudden death due to a stroke
However, if a large stroke happens in a part of the brain vital to breathing or the heart, it can lead to death in a short time. If the stroke is very large, it can cause widespread damage that the brain can't survive even if the cause of a clot or a bleed is treated.

16) B) abnormal thickening of the left ventricle wall.

Explaination:

- Hypertrophic cardiomyopathy is usually caused by abnormal genes (gene mutations) that cause the heart muscle to grow abnormally thick ( ventricles especially left ventricle or lower lobe). People with hypertrophic cardiomyopathy also have an abnormal arrangement of heart muscle cells (myofiber disarray). This disarray can contribute to arrhythmia in some people.

17) C) Left ventricle

Explaination:

- Myocarditis is a disease that causes inflammation of the heart muscle (left ventricle).

This inflammation enlarges and weakens the heart, creates scar tissue and forces it to work harder to circulate blood and oxygen throughout the body.

13) Hypertrophic cardiomyopathy

Explaination:

Hypertrophic cardiomyopathy is usually caused by abnormal genes (gene mutations) that cause the heart muscle to grow abnormally thick. People with hypertrophic cardiomyopathy also have an abnormal arrangement of heart muscle cells (myofiber disarray). This disarray can contribute to arrhythmia in some people.
Sudden death in hypertrophic cardiomyopathy rarely associated with exercise. Sudden cardiac death (SCD) is a relatively common cause of mortality in patients with HCM. It is caused by fatal arrhythmias which can be effectively treated with implantable cardioverter defibrillators (ICDs).
