Q

What is stable angina? Is it common or uncommon? What has not changed?

A

Stable angina chest pain with stress and activity. It is the most common type of angina in the United States. It follows a pattern that has been consistent for at least 2 months. That means the following factors have not changed:
* How often your angina events occur
* What causes or triggers your angina
* How long your angina events last
* How well your angina responds to rest or medicines

Q

What is Unstable Angina?

A

does not follow a pattern. It may be new or occur more often and be more painful than stable angina. Unstable angina can occur with or without physical exertion. Rest or medicine may not relieve the pain

Location of murmer
* Why is location important?

A

The anatomic location where the murmur is best heard is an important factor in determining the etiology of the lesio

81
Q

What are all the different locations of listening points of the heart?

A
  • A = aortic valve post (right upper-sternal border or RUSB)
  • P = pulmonic valve post (left upper-sternal border or LUSB)
  • T = tricuspid valve post (left lower-sternal border or LLSB)
  • M = mitral valve post (apex)
  • E = “Erb’s point”
82
Q

Both the aortic and pulmonic listening posts are considered what?

A
86
Q

Dynamic Cardiac Maneuvers

Dynamic/improved auscultation
* Can be more accurate than what?
* Changes what?

A
  • Can be more accurate than traditional method for dx of origin

92
Q

Squatting
* What murmur is decreased? Why?

A
93
Q

Squatting
* What is preload?
* What is afterload?

A

Q

standing:
* Decreases what?
* What murmur is increase? Decreased?

A
95
Q

Valsalva
* Increases what pressure?
* What is markedly decreased?
* What happens to murmers? What is the exception?

A
96
Q

Valsalva
* Perform for how long? why?

A

Perform only for MAX 10 seconds as these two murmurs will decrease over time and you don’t want to decrease cerebral and coronary blood flow for extended time

97
Q

What is this:
* high-pitched, “diamond shaped” crescendo-decrescendo, midsystolic ejection murmur heard best at the right upper sternal border radiating to the neck and carotid arteries.

A

Aortic stenosis

98
Q

What is this:
◦ high-pitched, “blowing” holosystolic murmur best heard at the apex.

A

◦ Mitral regurgitation

99
Q

What is this:
* soft, high-pitched, early diastolic decrescendo murmur heard best at the 3rd intercostal space on the left (Erb’s point) on end expiration, with the patient sitting up and leaning forward.

A

Aortic regurgitation

Q

The role of wearable and implantable monitors

What is the pro and cons of 30 day event monitor?

A
  • Pro: prolonged rhythm monitoring, smaller device, less leads to wear
  • Cons: only records when triggered by patient or with auto trigger, no getting the area wet, interpreting report
105
Q

The role of wearable and implantable monitors

What are the pros and cons implantable loop recorder?

A
  • Pro: Multiple companies with products, evaluates rhythm continuously and can be patient activated as well, lasts for up to 3 years, small, does not disrupt every day life
  • Cons: Surgical procedure to implant, may have monthly co- payments for monitoring services, interpreting results monthly

Q

Echocardiography (Echo)
* What are the two types?
* Ultrasound transducer placed where?
* Indicated in patients that need to detect what?
* Assess the function of what?
* Provides what?

A
  • Transthoracic (TTE) vs Transesophageal (TEE)
  • Ultrasound transducer placed various positions on anterior chest and obtain cross-sectional images of the heart and great vessels.
  • Indicated in patients that need to detect anatomic abnormality of the heart and great vessels.
  • Assess the function of cardiac chambers and valves through the cardiac cycle
  • Provides objective measurements
