The main class of drug for the treatment and management of Angina attack is what?

Diuretics are medicines that help the kidneys get rid of excess water and salt, which can ease the symptoms of heart failure, such as breathlessness and swelling.However, diuretics may have some side effects, such as loss of potassium, which can affect the heart and require regular blood tests and dietary changes.Diuretics can also cause other electrolyte abnormalities, such as hyponatremia, hypomagnesemia, hypocalcemia, and metabolic alkalosis. Electrolyte disturbances can have serious consequences for the heart function and rhythm, as well as other organs.

Choice A is wrong because fluid retention is the opposite of what diuretics do.

Diuretics reduce fluid retention by increasing urine output and decreasing blood volume.

Choice B is wrong because hypotension is not a direct effect of diuretics on the heart, but rather a consequence of reduced blood volume and vasodilation.

Hypotension can occur with diuretic use, especially if the dose is too high or the patient is dehydrated, but it is not a specific condition caused by diuretics.

Choice C is wrong because hyperglycemia is not related to diuretics or heart failure.

Hyperglycemia is a condition of high blood sugar, which can be caused by diabetes or other factors.

Diuretics do not affect blood sugar levels directly, although some diuretics may interact with diabetes medications and affect their efficacy.

Pentoxifylline is a medication that improves blood flow and oxygen delivery to the tissues in patients with peripheral vascular disease (PVD), a condition that causes narrowing of the arteries in the legs.Pentoxifylline can help reduce the symptoms of intermittent claudication, which is cramping pain in the legs that occurs with walking and improves with rest.

Choice A is correct because smoking is a major risk factor for PVD and quitting smoking can improve blood flow and prevent further damage to the arteries.

Choice B is correct because prolonged sitting or standing can reduce blood flow to the legs and worsen symptoms of PVD.

Patients should avoid crossing their legs, wearing tight clothing, or exposing their legs to cold temperatures.They should also elevate their legs when resting and move them frequently.

Choice C is wrong because pentoxifylline should be taken on an empty stomach, at least one hour before or two hours after meals, to increase its absorption and effectiveness.

Choice D is wrong because physical activity is beneficial for patients with PVD and intermittent claudication.

Exercise can improve blood circulation, increase muscle strength, reduce pain, and lower cardiovascular risk factors.Patients should be encouraged to walk regularly, as tolerated, and follow a supervised exercise program if available.
