Flashcards in Cardiac Manifestations Laboy Deck (23):
1

How can a systemic disease affect the heart?

-Increase demands on heart
-Cause arrhythmias
-Cause IHD and CAD
-Distort cardiac structure

2

DM is what type of risk factor for CAD, PAD, HF, MI and CVD?

Independent

3

What is the MC cause of death in DM 1 and 2?

CAD

4

Why do DM patients present atypically in IHD?

-Cardiac autonomic neuropathy from hyperglycemia
-Results in silent MI

5

What are "angina equivalent" symptoms in DM pts?

Nausea, dyspnea, pulm edema, arrhythmias, heart block, syncope

6

How does CAD develop in DM pts?

-Increased insulin resistance
-Endothelial dysfunction
-Thrombosis formation and platelet dysfunction

7

How does cardiomyopathy develop in DM?

DM triggers increased intra-ventricular collagen/fibrosis/inflammation (causes diastolic HF early on)

8

Hyperdynamic precordium is a cardiac manifestation of which systemic disease?

Hyperthyroidism

9

Cardiac symptoms a/w hyperthyroidism will respond to which medication?

PTU

10

Angina pectoris in hypothyroidism

Usually NOT experienced (low metabolic demands in hypothyroid)

11

How does protein energy malnutrition affect the heart?

-Myocardial atrophy
-Ventricular hypokinesis
-Systolic BP
-Generalized edema

12

What deficiency is found in many heart failure patients?

Thiamine (B1)

13

What deficiency is common in alcoholics?

Thiamine (B1)

14

Homocysteine and heart disease

Elevated homocysteine is an independent risk factor for athero

15

Deficiency in B6, 9 and 12 is inversely related to:

Homocysteine levels

16

How does obesity cause cardiac problems?

-Greater total blood volume to supply excess adipose tissue
-Heart is over burdened by having to pump blood against increased mass (afterload)

17

Chronic blood volume overload leads to:

HTN
Exertional dyspnea (pulm congestion)

18

What is the MC cause of death in RA?

CV disease

19

What is the MC cardiac finding in RA?

Pericarditis

20

What is the MC cardiac complication of SLE?

Pericarditis

21

What layers of the heart can SLE affect?

ALL layers

22

What causes acute rheumatic fever?

Group A beta-hemolytic strep (GAS) upper airway infection (aka strep throat)

23

What is the MC cardiac manifestation of rheumatic heart disease?

Valvular
