Q

how does atrial fibrillation happen?

A

when the electrical signals in the top chambers (atria) of your heart do not get sent out properly. They should be steady and regular, but instead they quiver or twitch (fibrillation). This causes your heart to beat randomly, which means it does not pump blood as well as it should.

Q

what is Abdominal aortic aneurysm?

A

Your abdominal aorta is usually about 2cm wide or about the width of a garden hose. If you have an aneurysm it can grow from 3cm to over 5.5cm wide.

Q

what is the treatment of abdominal aortic aneurysm?

A

no treatment is required if t is under 4.4cm
however if it is over:

endovascular repair (EVAR) is a type of keyhole surgery. This involves placing a stent-graft (a small metal tube covered with a mesh) inside the artery through a small cut in the groin

surgical repair involves replacing the affected part of your aorta with a plastic tube (graft).

A

happen when an artery supplying blood to your brain is blocked by a blood clot (gel-like clumps of blood).

54
Q

what is a haemorrhagic stroke?

A

happen when a blood vessel ruptures (or bursts), causing a bleed in the brain. This means less blood gets to the surrounding brain cells, causing them to die.

55
Q

If you have high cholesterol levels
If you have diabetes
If you have a type of irregular heartbeat called atrial fibrillation (A

57
Q

what is a heart block?

A

Electrical impulses (signals) move through your heart, which make it beat. A heart block happens when these electrical impulses are blocked or delayed.

58
Q

what causes a heart block?

A

Heart block is often caused by an underlying heart condition or other issues that can affect your heart’s electrical system. The specific cause of heart block will depend on the type you have. Causes may include:

coronary heart disease
congenital heart disease
cardiomyopathy
ageing of the electrical pathways in your heart
thickening of the heart muscle
some medicines.

59
Q

what is a AV heart block?

A

An AV heart block happens when the electrical impulses are delayed or blocked as they travel between your atria (the top chambers of your heart) and your ventricles (the bottom chambers of your heart).
first degree, second and third (complete block)

60
Q

what is a bundle branch block?

A

your electrical impulses that travel through the ventricles (the bottom chambers of your heart) are slower than normal. This happens because of a block in the path that your electrical impulses follow.

61
Q

what is tachybrady syndrome?

A

when your heart’s sinus node, which tells your heart when to beat, does not work properly.

If your heart’s sinus node does not work properly, your heartbeat can become too fast or too slow, or switch between fast and slow rhythms.

62
Q

what are symptoms of a heart block?

A

feeling faint or dizzy
feeling tired and sometimes confused
feeling a pressure or pain in your chest
being short of breath.

63
Q

A

pacemaker

64
Q

A

When your heart isn’t pumping blood as well as it should, it means you’re not getting enough oxygen.

65
Q

what are the symptoms of heart failure?

A

fainting or feeling lightheaded
feeling increasingly tired or weak at rest which gets worse with movement
new persistent cough
shortness of breath when you’re active or resting
swelling in your feet and ankles which can spread to your lower body.

66
Q

what are the causes of heart failure?

A

heart attack, cardiomyopathy, high blood pressure

67
Q

what is a heart attack?

A

where the supply of blood to the heart is suddenly blocked

68
Q

what are the causes of a heart attack?

A

conorary heart disease
CHD causes your coronary arteries to become narrowed by a gradual build-up of fatty deposits called atheroma.

If a piece of atheroma breaks off, a blood clot forms around this to try and repair the damage to the artery wall. This clot can block your coronary artery, causing your heart muscle to be starved of blood and oxygen.

or hypoxia

69
Q

how would you treat a heart attack?

A

stent into the blocked artery to keep it opened.

thombolysis- clot disolving

70
Q

what is hypertension?

A

blood pressure is always too high. This means your heart is working harder when pumping blood around your body.

71
Q

what is the difference between systolic and diastolic?

A

Systolic pressure: this is the higher of the two numbers. It’s the pressure against your arteries when your heart is pumping blood around your body.

Diastolic pressure: this is the lower of the two numbers. It shows how much pressure is in your arteries when your heart relaxes between beats.

72
Q

what is the risk of hypertension?

A

your arteries lose their stretchiness, becoming stiff or narrow.

This narrowing makes it easier for fatty material (atheroma) to build up. This narrowing and damage to the arteries lining your heart or brain could trigger a life-threatening heart attack or stroke.

73
Q

what is heart valve disease?

A

when 1 or more of you heart valves dont work.

74
Q

what are the 2 types of heart valve disease?

A

Valve stenosis or narrowing means the valve does not open fully, it can block or restrict the flow of blood.
Valve regurgitation, incompetence or leaky valve means the valve does not close fully and the blood can leak back into the heart instead of forwards into the body.

75
Q

what are the causes of heart valve disease?

A

being born with an abnormal valve (congenital heart disease), such as bicuspid aortic valve
if you’ve had rheumatic fever
cardiomyopathy, a disease of the heart muscle
damage to the heart muscle from a heart attack
getting older
infection to your heart (endocarditis).

76
Q

what is high cholesterol?

A

to much fatty substance in the blood. can be at risk of a heart attack or stroke

77
Q

what is secondary hypertension?

A

Secondary high blood pressure (secondary hypertension) is high blood pressure that’s caused by another medical condition. It can be caused by conditions that affect the kidneys, arteries, heart or endocrine system. Secondary hypertension can also occur during pregnancy.

78
Q

what are examples of some conditions that can give you secondary hypertension?

A

Kidney disease.
Adrenal gland disorders.
Hyperthyroidism.
Stricture of the aorta
Nervous
Alcohol
Obesity
Pregnancy
Drug treatment

79
Q

what is pulmonary hypertension?

A

Pulmonary hypertension is high blood pressure in the blood vessels that supply the lungs (pulmonary arteries). which can affect the right side of the heart. The reduced blood flow makes it harder for the right side of the heart to pump blood through the arteries.

If the right side of your heart has to continually work harder, it can gradually become weaker. This can lead to heart failure.

80
Q

what is left ventricle failure?

A

when the left ventricle, the heart’s main pumping power source, is gradually weakened. so the heart has to work harder.

81
Q

what happens why systolic left ventricle failure occurs?

A

When systolic failure occurs, the left ventricle cannot contract forcefully enough to keep blood circulating normally throughout the body, which deprives the body of a normal supply of blood. As the left ventricle pumps harder to compensate, it grows weaker and thinner. As a result, blood flows backwards into organs, causing fluid build-up in the lungs and/or swelling in other parts of the body.

82
Q

what happens when left sided diastolic occurs?

A

When diastolic heart failure occurs, the left ventricle has grown stiff or thick, and it is unable to fill the lower left chamber of the heart properly, which reduces the amount of blood pumped out to the body.
Over time, this causes blood to build up inside the left atrium, and then in the lungs, leading to fluid congestion and symptoms of heart failu

83
Q

what is right ventricle failure?

A

the muscle of your right ventricle is not pumping as efficiently as it should be. This can be caused by a number of conditions, including left-sided heart failure, high blood pressure in the lungs and heart valve disease

84
Q

what is systolic heart failure?

A

the heart cannot effectively contract with each heartbeat.

85
Q

what is diastolic heart failure?

A

your heart cannot relax between heartbeats.

86
Q

what is aneurysyms?

A

abnormal bulge or ballooning in the wall of a blood vessel. An aneurysm can burst. This is called a rupture. A ruptured aneurysm causes bleeding inside the body and often leads to death.

87
Q

what causes aneurysms? what vessel is it most common in?

A

congenital defects, trauma, infections, atherosclerosis.

aorta

88
Q

what is fusiform aneurysms?

A

the wall of the artery expands until it bursts. It can be repaired if known about. A mesh is applied around the artery to reinforce it and stop it from expanded further.

89
Q

what is dissecting aneurysms?

A

These are in the highest-pressure areas normally (aorta). There will be a split in the inner lining, the blood will push out and will strip the layers apart and the blood will end up around the artery instead of inside it. These are extremely painful. If a patient has one, for example, it most likely occurs around the arch of the aorta, but it does not necessarily fill with blood there and may do further down (abdo) resulting in a pulsating mass.

90
Q

what is saccular/berry aneurysms?

A

This is one particular part of the artery wall has failed and forms a berry shape. These can be repaired but a clip along the bottom where it joins the main artery. The idea is without an active blood supply, the blood in the aneurysm will be reabsorbed into the artery, but this takes time. If these burst, the blood will irritate the brain and it will swell, quickly raising intercranial pressure.

91
Q

what is the risk of aneurysms?

A

Thromboembolism: depending on where the clot has travelled to, thromboembolism can cause pain in the extremities or the abdo (will have ripping/tearing pain, pain will not get better or worse and is usually a 10/10 pain)
Stroke: if a clot travels to the brain, it can cause a stroke
Severe chest and/or back pain: if an aortic aneurysm in the chest ruptures
Angina: certain types of aneurysm can lead to angina – the pain is related to narrowed arteries supplying the heart itself
Sudden extreme headache: if a brain aneurysm leads to subarachnoid haemorrhage the main symptom is sudden extreme headache; often unlike any previous experience of head pain

92
Q

what is pericarditis?

A

Pericarditis is inflammation of the lining around your heart, which causes chest pain.

93
Q

what is cardiac tamponade?

A

obtain and record base line observations,
consider PPCI in suspected STEMI.

Q

whats the difference between stable and unstable angina?

A

unstable is indicating obstruction and is more serious, noticeable changes in frequency, intensity and duration of pain. may occur at rest sleep and walking.
pain may be apparent without exertion.
may act as a warning of MI and is know as pre infarction.

102
Q

what are symptoms of unstable angina?

A

retrosternal pain (behind the breast bone) described as heaviness in the arms or chest.
pain may be referred to the throat, jaw and teeth, also armpits and into the arm,
nausea/vommiting,
pallor/ diaphoresis.

103
Q

what are clinical presentations of stable angina?

A

pain related on exertion,
pain normally subsides on resting within a few minutes and therefore would not be categorized as ACS.
if pain persists for over 15 minutes treatment then could be ACS.

104
Q

what are clinical presentations of a MI?

A

severe central chest pain, may radiate to one or both sides of the chest, into neck, jaw, arms and back, described as a crushing nature.
pale, diaphoresis (sweating), faintness, giddiness, nausea and vomiting.
hypo/hypertension
sense of impending doom,
shallow breathing, grey with cyanosed exremities,
sometimes a irregular pulse, ecg irregulartities

105
Q

what are causes of heart failure?

A

mi,
myocarditis,
hypertension,
valvular heart disease,
left and right sides of the heart can fail separately or simultaneously.

106
Q

what is left ventricular failure?

A

The failure of the left ventricle to function effectively enough to act as an efficient pump, causing an excessive volume of fluid to accumulate in the pulmonary circulation
Left ventricle damaged = inability to pump out all the blood being returned to it from the lungs
Blood backs up causing a rise in pressure in the left atrium and pulmonary veins
Pulmonary veins become engorged forcing serum out of the capillaries into the alveolar spaces
Air mixes with serum, producing foam
Gaseous exchange impaired
Can often be acute
May accompany a myocardial infarction

107
Q

what can left ventricular failure present itself as:

A

pulmonary oedema (excess water in the lungs),
dyspnea, orthopnoea- shortness off breath when lying flat,
cough frothy pink sputum,
abnormal lung sounds such as wheezing and crackling,
distended neck veins.
agrivation and confusion,
tachycardia,
hypertension

108
Q

what is right ventricular failure?

A

Failure of the right ventricle to function effectively enough to act as an efficient pump, causing an excessive volume of fluid to accumulate in the systemic circulation

109
Q

what happens in the heart in right ventricular failure?

A

Blood backs up, causing a rise in pressure in the right atrium and systemic veins

The systemic veins become engorged, pressure in the systemic veins increases, forcing serum out of the veins into the surrounding tissue

110
Q

how would you manage cardiac tamponade?

A

continuous monitoring,
administer oxygen at high flow rates,
initiate iv access if required
patient will require pericardiocentesis- draining of the fluid

111
Q

what is rheumatic fever?

A

serious complication that can develop following an untreated throat infection.
causing inflammation of the tissues and organs

112
Q

what are symptoms of rheumatic fever?

A

joint pain, swelling, inflammation of the heart causing chest pain and shortness of breath

113
Q

what is cardiac tamponade?

A

an accumulation of blood in the pericardial sac causing an increase in pericardium pressure.
this does not allow the heart to expand and refill properly resulting in decrease stroke volume and cardiac output.

114
Q

what are signs and symptoms of cardiac tamponade?

A

muffled heart sounds, narrowing pulse pressure, hypotension, distended neck veins, extreme drop in blood pressure and diaphoresis (sweating) pallor (pale appearance), tachycardia

115
Q

how would you manage a patient with cardiac tamponade?

A

administer oxygen at high flow rates, initiate iv access if required, patient will require pericardiocentesis (using a needle to get rid of the fluid.)

116
Q

what is pericarditis?

A

swelling of the pericardium, which is the fluid filled sac surrounding the heart. due to an infection

117
Q

what are some causes to pericarditis excluding infection?

A

heart attack, heart surgery, trauma to the chest esophagus or the heart.
swelling or inflammation of the heart muscle
certain medications including cancer treatment.

118
Q

what are the symptoms of cardiac tamponade?

A

chest pain which may also be felt in the neck, back, shoulder or abdomen.
pain that increases with deep breathing and swallowing.
sharp stabbing pains,
fever, chills or sweating,
pain gets worse when lying on back and relieved when sitting forwards and bending forwards.

119
Q

how would you manage a patient with cardiac tamponade?

A

administer oxygen as per guidelines,
give analgesia (relieve pain, reduce inflammation)
transport to hospital.

120
Q

what is suspect acute limb ischaemia?

A

a sudden onset of leg pain or sudden deterioration in claudication (muscle pain). associated with a loss of pulses and pallor (pale).
features such as coldness and cyanosis of the limb. (purple) or loss of muscular power and sensation

121
Q

what is suspect chronic limb ischaemia?

A

when there is a progressive development of cramp like pain in the calf, thigh or buttock on walking which is relieved by resting.
unexplained foot or leg pain
or non healing wounds on the lower limb.

122
Q

what is the difference between ischemic to embolus compared to thrombosis?

A

embolus:
onset is acute,
limb appears white (due to no circulation),
vascular elimination in the other leg is usually normal.

thrombosis:
onset is more gradual,
the leg may not be white and symptoms may be less severe,
presentation is usually with worsening claudication (muscle pain) and rest pain

123
Q

how would you do a physical assessment of ischemic limbs?

A

pain- constant present and persistent
pulseless- ankle pulses are always absent
pallor (pale) blue or purple limbs
power loss or paralysis
reduced sensation or paresthesia (abnormal sensation)
perishing with cold

124
Q
A
