CARDIOLOGY Flashcards

1
Q

differences between STEMI and NSTEMI

A

STEMI: ST elevation +elevated troponin. Complete occlusion of blood vessels resulting in necrosis of myocardium

NSTEMI: ST depression + elevated troponin, partial occlusion of blood vessels resulting in necrosis of myocardium

Q

differences between stable and unstable angina

A

stable: exercise induced, no minimal ECG changes with no changes in troponin
unstable: often occurs while resting, sleeping or minimal physical activation. ST depression with no changes in troponin. Can lead to heart attack

Q

Which heparin should be used? how long should they be one this ?

A

UFH: STEMI patient receiving fibrinolytic.
LMWF ( enoxaparin has been shown to be superior to UFH in patients treated with tenecteplase

Heparins should be continued for a minimum of 48 hours ( or until PCI) and use can be extended in patients with high-risk features.

71
Q

when is fenofibrate useful

72
Q

what is 3 types heart failure

A

impaired inability to fill with ( diastole) or eject ( systole) blood

1: HF with preserve LVEF ( diastolic dysfunction): filling problems due to HTN ( LVEF >/50%)
2: HF with midrange EF ( LVEF 41-49%)
3: HF with reduced LVEF ( systolic dysfunction): pumping problems ( <40% )

73
Q

to compensate for decrease CO, body respond with 4 mechanisms

A

1: stimulation of RAAS: retains water and constricts blood vessels ( increase after load and preload)
2: increased SV ( stroke volume) to increase CO ( increase preload)

3: enlarging ventricular walls to increase Force of contract ( hypertrophy)
4: Increased HR to increased CO ( preload and after load)

74
Q

symptoms of hF

A

hypotension, dyspnea, systemic congestion, peripheral edema

75
Q

non-pharm treatment for HF

A
salt restriction ( <2-3 g of Na+/day) 
fluid restriction: 2L/ day from all sources 
monitor weight 
treat risk factors: HTN, diabetes ( risk of HF reduced by 50% by managing HTN along :)
76
Q

A

I: No symptoms with ordinary activity

II: Symptoms occur with ordinary activity ( SOB)

III: Symptoms occur with less than ordinary activity

IV: Symptoms occur at rest or with minimal activity

77
Q

What is treatment for midrange and persevere EF

A

symptomatic relieve: diuretic for congestion and managing risk factors

78
Q

treatment for HF-rEF

A

ACE-I OR ARB OR ARNI
BB ( metoprolol, carvedilol and bisoprolol)
MRNA
SGLT2I ( dapa and empa)

79
Q

what is the role of ivabradine?

A

sinus rhythm with a resting heart rate ≥77 bpm

80
Q

what is the role of nitrates/ hydralazine

A

reduces mortality and morbidity in black patients with NYHA class III–IV HF and is recommended in addition to standard therapy (ACE inhibitor, beta-blocker with or without MRA) in this settin

81
Q

which ARBs showed decreased in mortality with HF

A

candesartan and valsartan

82
Q

switching from ACE-I to ARNI

A

washout period of 36h required when switching from ACE to ARNI but no washout required when switching from ARB

83
Q

what is the role of digoxin in HF? what is the usual dose range

A

** does not reduce mortality

considered in Ventricular rate control in patient with AF not controlled on BB or who cannot tolerate BB

0.0625–0.25 mg daily

84
Q

target trough levels for digoxin and when should we measure them

A

Measure trough serum concentrations at least 8 hours after administration and adjust the dose to maintain the serum concentration between 0.6 and 1.2 nmol/L

85
Q

which drug do not show reduce mortality in HF

A

diuretics ( furosemide)

digoxin

86
Q

what is systolic and diastolic BP

A

systolic: heart muscles contract causing elevated BP since blood is pumped out of the heart
diastolic: heart muscle relaxes and decrease BP as blood fills the heart

87
Q

know values for:
isolated systolic HTN
hypertensive emergency
hypertensive urgency

A

isolated: >140/ <90 mmhg
emergency: >180/120 mmHg with organ damage
hypertensive urgency: >180/120 mmhg and no organ damage

88
Q

what is blood pressure?

A

BP= cardiac output (CO) x systemic vascular resistance ( SVR)

89
Q

explain the RAAS system

A

kidney releases renin in response to hypotension, sympathetic stimulation and decreased blood flow to the kidneys
angiotensin II: increased cardiac contractility and CO
increased aldosterone synthesis–> increased Na/H20
vasoconstriction –> increased SVR ( systemic vascular resistance)

90
Q

resistant hypertension

A

bp above target while on 3 or more BP at optimal doses
