Chest pain Flashcards

1
Q

What are some potentially life-threatening cardiac and pulmonary conditions that must be considered in the work-up of patients with chest pain?

How often are these diagnosed in children presenting with chest pain?

A

potentially life-threatening cardiac conditions (eg, hypertrophic cardiomyopathy, myocarditis, or myocardial ischemia) and serious pulmonary conditions (eg, acute chest syndrome in patients with sickle cell disease, spontaneous pneumothorax, or pulmonary embolus) are found in 1 to 6 percent of pediatric patients with chest pain depending upon the setting

35
Q

How might CHD with LV outflow obstruction cause chest pain in kids? Which lesions might cause this?

A

Hypertrophic cardiomyopathy, aortic stenosis (subvalvar, valvar, or supravalvar), or coarctation of the aorta may cause decreased coronary blood flow and angina

36
Q

Describe how coronary artery anomalies might cause chest pain in children

A
  • congenital and acquired conditions (eg, coronary artery aneurysm or stenosis caused by Kawasaki disease) and may present with chest pain on exertion.
  • Anomalous origin of the left coronary artery from the main pulmonary artery usually presents in infancy, but can become symptomatic later in childhood. In that disorder, left ventricular ischemia usually results in cardiomyopathy and mitral regurgitation.
  • Origin of a coronary artery from the contralateral sinus of Valsalva and coursing of the anomalously positioned coronary artery between the aorta and pulmonary artery can be associated with exertional chest pain. In these patients, the pain is caused by compression of the coronary artery between the distended great arteries with the increased cardiac index associated with exercise with the following anatomic variants:

●Slit-like coronary orifice

●Acute angle of take-off of the coronary artery

●Presence of an intramural segment

37
Q

Risk factors for classic angina?

A
  • hyperlipidemia
  • prior Kawasaki disease with coronary artery aneurysms or stenoses
  • collagen vascular disease (eg, systemic lupus erythematosus)
38
Q

Symptoms and ECGs findings of classic angina?

A

crushing or squeezing substernal chest pain with radiation to the jaw or left arm and associated with diaphoresis, nausea and vomiting, difficulty breathing, or altered mental status. An electrocardiogram (ECG) obtained while the patient has pain often shows ST wave elevation or depression

39
Q

Describe variant angina. How does it present and what ECG findings are there?

A

Coronary vasospasm (variant angina) and myocardial infarction are rare causes of chest pain in children and adolescents. Coronary vasospasm is associated with angina, transient ischemic changes on ECG during episodes of pain, cardiac enzyme elevation, and ST-segment elevation on ambulatory ECG monitoring. Variant angina with myocardial infarction has been described after recreational use of cocaine, amphetamines, bath salts (methcathinones), marijuana, and synthetic cannabinoids in adolescents.

40
Q

What are the major clinical manifestations of pericarditis?

A

●Chest pain that is typically sharp, increased with inspiration, improved by sitting up and leaning forward, worsened by lying down, and occasionally radiates to the left shoulder

●Pericardial friction rub described as a superficial scratchy or squeaking sound best heard with the diaphragm of the stethoscope over the left sternal border during the systolic, diastolic or both phases of the cardiac cycle

●Electrocardiographic (ECG) changes such as new widespread ST elevation or PR depression; later in the course there is T wave inversion

●Distant heart sounds and/or pulsus paradoxus suggesting pericardial effusion

41
Q

What are some of the etiologies of pericarditis?

A

Pericarditis may be of infectious origin (eg, nonspecific viral, bacterial, tuberculous, or secondary to human immunodeficiency virus), associated with open heart surgery (post-pericardiotomy syndrome), or complicate an underlying condition such as collagen vascular disorder, uremia, neoplasm, or trauma

42
Q

How might viral myocarditis present?

A

Viral myocarditis in children, which is usually painless, may occasionally cause chest pain when concomitant pericarditis is present. Children with myocarditis also may display tachycardia that is out of proportion to fever or persistent while quiet or asleep, respiratory distress, signs of heart failure, poor perfusion, and atrial or ventricular arrhythmias

43
Q

What additional symptoms other than chest pain might dilated cardiomyopathy present with?

A

Children with dilated cardiomyopathy can develop chest pain in association with syncope, decreased exercise tolerance, and heart failure symptoms (eg, orthopnea or dyspnea on exertion). From 20 to 50 percent of patients with dilated cardiomyopathy have an inherited form. A family history of heart failure before the age of 60 years or sudden death suggests a genetic cause.

44
Q

How might tachyarrhythmias present as chest pain?

A

Tachyarrhythmias (eg, supraventricular tachycardia with or without underlying Wolff-Parkinson-White syndrome, ventricular tachycardia) are usually painless, but, if sustained, may cause angina. Some children may also experience the sensation of palpitations associated with tachyarrhythmias or premature beats and report this sensation as chest pain

45
Q

How might aortic root dissection present?

A

Aortic root dissection causes an abrupt onset of severe sharp or tearing pain that may be localized to the anterior chest (ascending aortic dissection) or posterior chest (descending aortic dissection) with radiation to other parts of the chest, back or abdomen. It is associated with Marfan syndrome, Turner syndrome, type IV Ehlers-Danlos syndrome, homocystinuria, rare familial aortopathies, or cystic medial necrosis.

46
Q

What is a ruptured sinus of valsalva aneurysm?

A

Ruptured sinus of Valsalva aneurysm is a rare condition caused by congenital absence of media in the aortic wall behind the sinus of Valsalva. The aneurysm typically ruptures into the right ventricle or right atrium but can affect the other chambers or pulmonary artery and cause a continuous murmur and heart failure

47
Q

What are etiologies of chest pain that are non-cardiac?

A

Spontaneous pneumothorax

PE

Pulmonary HT

Acute chest syndrome (sickle cell) - chest pain plus new pulmonary infiltrate involving at least one complete lung segment (not atelectasis), temperature >38.5ºC, and tachypnea, wheezing, or cough

Airway foreign body

Tumor

Oesophageal rupture (boerhaave syndrome)

48
Q

What are some of the common causes of paediatric chest pain?

A

Specific diagnoses, from most to least frequent, include the following:

●Musculoskeletal conditions (eg, costochondritis, muscle strain, or trauma)

●Psychogenic conditions (eg, panic attack, hyperventilation syndrome, or psychosomatic complaints)

●Respiratory conditions (eg, asthma, pneumonia, or pleuritis)

●Gastrointestinal disease (eg, gastroesophageal reflux, esophagitis, or gastritis)

●Breast disease

●Skin infections

49
Q

Costochondritis

pectus carinatum

50
Q

List some GIT causes of chest pain in children

A

GORD

Medication-induced ‘pill’ oesophagitis

oesophageal foreign body

51
Q

What is pleurodynia?

A

Pleurodynia refers to an acute illness with marked paroxysmal spasms of the muscles of the chest and abdomen and fever. It most commonly occurs in association with group B coxsackie viruses. In children, characteristic vesicular stomatitis and rash on the palms and soles of the feet are often present as well . Most patients are ill for four to six days

52
Q

What neurological disorders may present as chest pain?

A

Chest pain rarely is caused by a neurologic disorder that affects one or more costal nerves. As an example, herpes zoster in a dermatomal distribution on the chest can cause pain, which may be manifest before lesions appear. Spinal cord compression, which may be caused by tumor or vertebral collapse, or epidural abscess is also a rare cause of radicular chest pain
