Which of the following initiates the process of atherosclerosis?

Which of the following events initiates the process of atherosclerosis? Endothelial injury and the subsequent release of cytokines are the events that initiate atherosclerosis. Smooth muscle proliferations, fibrosis, and calcification in atherosclerosis all reduce the size of the blood vessel lumen.

Considering this, which of the following white blood cells play a role in the fatty streak in atherosclerosis?

The main white blood cell that plays a role in the development of the fatty streak in atherosclerosis is the: macrophage. Macrophages phagocytose lipids in the tunica media of the vessel wall and accumulate, forming the fatty streak.

Likewise, which set of clinical manifestations is highly characteristic of a septic shock state? The set of symptoms that all manifest with septic shock consists of tachycardia in response to hypotension, generalized edema from increased capillary permeability, and warm skin due to peripheral vasodilation.

Also, which of the following conditions is caused by the collection of fluid in the pericardial sac potentially resulting in tamponade?

The causes of pericardial fluid accumulation leading to cardiac tamponade are idiopathic, infectious, immune-inflammatory, neoplastic disease, post-cardiac surgery, trauma, renal failure, aortic dissection and miscellaneous (chronic renal failure, thyroid disease, amyloidosis) [2-4].

Which patient has the highest risk of coronary artery disease CAD )?

The traditional risk factors for coronary artery disease are high LDL cholesterol, low HDL cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to Fisher. Obesity may also be a risk factor.

What is the primary mechanism of atherogenesis?

What is primary mechanism of atherogenesis? The oxidation of LDL is an important step in atherogenesis. Inflammations with oxidative stress and activation of macrophages is the primary mechanism.

Which of the following blood tests measures the percentage of erythrocytes in a given volume of blood?

Hematocrit (HCT, packed cell volume, PCV).
This test measures the amount of space (volume) red blood cells take up in the blood. The value is given as a percentage of red blood cells in a volume of blood. For example, a hematocrit of 38 means that 38% of the blood's volume is made of red blood cells.

What term should the nurse document for a detached blood clot?

What term should the nurse document for a detached blood clot? A detached thrombus is a thromboembolus. A thrombus is a clot that remains attached to a vessel wall; a detached thrombus is a thromboembolus. An embolus is a bolus of material floating in the blood stream; a detached thrombus is a thromboembolus.

Which valvular condition is characterized by the valve opening being constricted and narrowed?

Aortic stenosis is one of the most common and most serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium.

Which valvular condition is characterized by the valve opening being constricted and narrowed causing the valve leaflets or cusps to fail to open completely?

Aortic valve stenosis — or aortic stenosis — occurs when the heart's aortic valve narrows. This narrowing prevents the valve from opening fully, which reduces or blocks blood flow from your heart into the main artery to your body (aorta) and onward to the rest of your body.

What does pericardial effusion sound like?

Physical Examination. A large pericardial effusion can muffle the heart sounds, making them soft or even inaudible. A pericardial friction rub from pericarditis may be present. Ewart's sign is dullness to percussion at the left lung base due to compressive atelectasis from a large pericardial effusion.

What is Pulsus Paradoxus?

Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mmHg. When the drop is more than 10 mmHg, it is referred to as pulsus paradoxus.

What is Beck's triad?

Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, an emergency condition wherein fluid accumulates around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds.

How does kidney failure cause cardiac tamponade?

Uremic pericarditis may complicate either acute or, more commonly, chronic renal failure. When dialysis is not employed, uremic pericarditis is usually a preterminal event and is characterized by a serofibrinous exudation of an amount inadequate to cause cardiac tamponade.

What are the complications of pericarditis?

Pericarditis may result in one of two serious complications: cardiac tamponade and chronic constrictive pericarditis.

Complications

  • Anxiety.
  • Breathing problems and chest pain.
  • Dizziness and fainting.
  • Swelling of the abdomen.
  • Drowsiness.
  • Weak pulse.

How do you do Pericardiocentesis?

During pericardiocentesis, a doctor inserts a needle through the chest wall and into the tissue around the heart. Once the needle is inside the pericardium, the doctor inserts a long, thin tube called a catheter. The doctor uses the catheter to drain excess fluid. The catheter may come right out after the procedure.

How do you check for Pulsus Paradoxus?

To measure the pulsus paradoxus, place a blood pressure cuff on the patients arm and very very slowly deflate the cuff while listening for brachial pulsations. Note the pressure that you first hear with pulsations during expiration (which will be the highest).

What type of shock is tension pneumothorax?

Obstructive

How is cardiac tamponade diagnosis?

Your doctor will conduct further tests to confirm a cardiac tamponade diagnosis. One such test is an echocardiogram, which is an ultrasound of your heart. Other diagnostic tests may include: a thoracic CT scan to look for fluid accumulation in your chest or changes to your heart.

What are the 3 stages of shock?

There are three stages of shock: Stage I (also called compensated, or nonprogressive), Stage II (also called decompensated or progressive), and Stage III (also called irreversible).

Why is sepsis increasing?

Staff shortages and hospital overcrowding have contributed to an apparent increase in sepsis death by more than a third in two years, according to a UK safety expert. The NHS classifies sepsis as a rare but serious complication of an infection, which can lead to multiple organ failure if not quickly treated.

How is sepsis detected?

If your doctor believes you might have sepsis, he'll do an exam and run tests to look for the following: Bacteria in the blood or other body fluids. The source of the infection (he may use an X-ray, CT scan, or ultrasound) A high or low white blood cell count.

What is the most common type of shock?

Hypovolemic shock is the most common type of shock and is caused by insufficient circulating volume. The most common cause of hypovolemic shock is hemorrhage (internal or external), however in children vomiting and diarrhea are the most common cause.

What is sepsis shock?

Septic shock is a severe and potentially fatal condition that occurs when sepsis leads to life-threatening low blood pressure. Sepsis develops when the body has an overwhelming response to infection.

What are the 6 signs of sepsis?

You must have one or more of the following signs to be diagnosed with severe sepsis:
  • patches of discolored skin.
  • decreased urination.
  • changes in mental ability.
  • low platelet (blood clotting cells) count.
  • problems breathing.
  • abnormal heart functions.
  • chills due to fall in body temperature.
  • unconsciousness.

What is the shock?

Shock is a life-threatening condition that occurs when the body is not getting enough blood flow. Lack of blood flow means the cells and organs do not get enough oxygen and nutrients to function properly. Many organs can be damaged as a result. Shock requires immediate treatment and can get worse very rapidly.

How do you prevent septic shock?

Septic shock can best be prevented by following these recommendations:
  1. Don't let your guard down. Take all infections seriously.
  2. Prevent infections through vaccination. Have your loved one vaccinated for both the flu and pneumonia.
  3. Regularly wash hands.
  4. Take care of any open wounds.

How many types of shocks are there?

There are four major types of shock, each of which can be caused by a number of different events.
  • Obstructive shock. Obstructive shock occurs when blood can't get where it needs to go.
  • Cardiogenic shock.
  • Distributive shock.
  • Hypovolemic shock.

What is the most important risk factor for coronary heart disease?

The traditional risk factors for coronary artery disease are high LDL cholesterol, low HDL cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to Fisher. Obesity may also be a risk factor.

Can an ECG detect a blocked artery?

An ECG (electrocardiogram) records the electrical activity of your heart at rest. However, it does not show whether you have asymptomatic blockages in your heart arteries or predict your risk of a future heart attack. The resting ECG is different from a stress or exercise ECG or cardiac imaging test.

How much artery blockage is normal?

A moderate amount of heart blockage is typically that in the 40-70% range, as seen in the diagram above where there is a 50% blockage at the beginning of the right coronary artery. Usually heart blockage in the moderate range does not cause significant limitation to blood flow and so does not cause symptoms.

How long does it take for heart disease to develop?

It develops often for decades before one develops symptoms, and so if we could really look inside the heart, we'd see that many people have coronary artery disease at a very young age, even in soldiers killed in battle in their late teen years or early twenties, often thickening of the coronary arteries has already

How can I check if my arteries are clogged?

Are there tests for clogged arteries?
  1. Cholesterol screening.
  2. Chest X-ray.
  3. CT scan.
  4. Ultrasound.
  5. Echocardiogram and/or cardiac stress test.
  6. Electrocardiogram.
  7. MRI or PET scanning.
  8. Angiogram.

What is the best test to check for heart problems?

Common medical tests to diagnose heart conditions
  • Blood tests. When your muscle has been damaged, as in a heart attack, your body releases substances in your blood.
  • Electrocardiogram (ECG)
  • Exercise stress test.
  • Echocardiogram (ultrasound)
  • Nuclear cardiac stress test.
  • Coronary angiogram.
  • Magnetic resonance imaging (MRI)
  • Coronary computed tomography angiogram (CCTA)

What are risk factors for coronary heart disease?

If you have risk factors for coronary artery disease — such as high blood pressure, high cholesterol, tobacco use, diabetes, a strong family history of heart disease or obesity — talk to your doctor.

What is a primary cause of coronary heart disease?

Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits.

How long can you live with coronary artery disease?

On average, women live longer than men with heart disease. At age 50 women can expect to live 7.9 years and men 6.7 years with heart disease.
