The correct answer for this question is
chest discomfort not relieved by rest or nitroglycerine.
A medical emergency is a heart attack. A blood clot generally causes a heart attack when it prevents blood from reaching the heart. Tissue loses oxygen and perishes without blood.
The chest, neck, back, or arms may feel tight or painful. Fatigue, dizziness, an irregular heartbeat, and anxiety may also be present. Compared to males, women are more prone to experience unusual symptoms.
The many forms of treatment include prescription drugs, stents, cardiac rehabilitation, and bypass surgery.
When the heart muscle's supply of oxygen is inadequate in one or more places, a heart attack (myocardial infarction) result. When the heart muscle's blood supply is restricted, this occurs.

Answer:
A. are difficult to distinguish from other illnesses is the correct answer.
Explanation:
Smoking cigarettes will kill you, but before you die, you could experience some pretty terrible diseases and health conditions from smoking. Here are some of the most gruesome diseases caused by smoking
1. lung cancer: More people die from lung cancer than any other type of cancer. Cigarette smoking is the number one risk factor for lung cancer; it's responsible for 87 percent of lung cancer deaths. Your chance of still being alive five years after being diagnosed is less than 1 in 5.
2. COPD (chronic obstructive pulmonary disease): COPD is an obstructive lung disease that makes it hard to breathe. It causes serious long-term disability and early death. COPD starts by making it hard to be active, such as playing with a grandchild, then usually gets worse, until climbing a short set of stairs or even walking to get the mail is exhausting or impossible. It can leave people stuck in their homes, unable to do the things they want or see friends. About 80 percent of all COPD is caused by cigarette smoking. COPD is the third leading cause of death in the United States.
3. Heart Disease: Smoking harms nearly every organ in your body, including your heart. Smoking can cause blockages and narrowing in your arteries, which means less blood and oxygen flow to your heart. When cigarette consumption in the U.S. decreased, so did the rates of heart disease. Yet, heart disease still remains the number one cause of death in the U.S.
4. stroke: Because smoking affects your arteries, it can trigger stroke. A stroke happens when the blood supply to your brain is temporarily blocked. Brain cells are deprived of oxygen and start to die. A stroke can cause paralysis, slurred speech, altered brain function and death. Stroke is the fourth leading cause of death in the United States and a leading cause of adult disability.
5. Asthma: Asthma is a chronic lung disease that makes it harder to move air in and out of your lungs—otherwise known as "breathing." Because cigarette smoke irritates air passages, it can trigger sudden and severe asthma attacks. Asthma is a serious health condition that affects more than 26 million Americans. Smoking only makes it worse.

As adults age, their dark adaption is slower; it takes longer to recover
their vision when going from a light to a dark area.
<h3>How does age affect dark adaptation?</h3>
- Results indicated that during human aging there is a dramatic slowing in a rod-mediated dark adaptation that can be attributed to delayed rhodopsin regeneration.
- Even in the absence of ocular disease, older adults have significant difficulty seeing in low light and at night.
- The severity of this issue cannot be explained by optical changes in the aging eye, such as pupillary miosis and increased lens density, and little is known about the neural basis of this issue.
- 94 adults between the ages of 20 and 80 had their dark adaptation functions measured in order to determine how quickly rod-mediated sensitivity recovered after being exposed to 98% bleach.
- In order to control for macular disease, fundus photography and a grading system were used to describe macular health in subjects over the age of 49.
