CARDIO MIDTERM EXAM Flashcards
It is characterized bv an elevation in mean pulmonary arterial pressure greater than 25 mmlic at rest or 30 mmHa during exercise. increased pulmonarv vascular resistance, and normal left heart ventricular function in the absence of other secondarv causes.
Pulmonary Hypertension
Pulmonary Hypertension associated with:
Congenital Heart Disease, Collagen vascular disease, liver cirrhosis,
viral infection
drug effects
more common among women than in men, with a ratio of 3 to 1.

rare and can occur at any age, although it is more common in the third and fourth decades.
Primary pulmonary hypertension
Primarv pulmonarv hvpertension is characterized by:
Dyspnea
Angina
Syncope
Cough, hemoptysis, hoarseness and Raynaud phenomenon
most common symptoms

normal chest radiographs.
High-resolution CT
life-threatening and
has poor prognosis

Digoxin
Refers to a disease state characterized by the presence of incompletely reversible airflow obstruction.
chronic obstructive pulmonary disease
(COPD), or
proposes a definition that focuses on the
progressive nature of airflow limitation and its association with abnormal inflammatory response of the lungs to various noxious particles or gases, primarily causes by smoking
Global Initiative for Chronic Obstructive Lung Disease (GOLD)
COPD is “a disease state characterized by airflow limitation that is not fully reversible.”
GOLD document
The chronic airflow limitation that is characteristic of COPD is caused by a mixture of small airways disease (e.g., obstructive bronchiolitis) and parenchymal destruction (emphysema),

TWO MAJOR DISEASES THAT MAKE UP COPD
Emphysema
Chronic Bronchitis
defined in condition characterized by abnormal, permanent enlargement of the airspaces beyond the terminal bronchiole, accompanied by destruction of the walls of the airspaces and loss of elastance
Emphysema
defined in clinical terms as a condition in which chronic productive cough is present for at least 3 months per year for at least 2 consecutive years.
Chronic bronchitis
Common denominator of the 3 diseases:
Airflow Obstruction
asthma is no longer conventionally considered to be part of the spectrum of COPD, the diagram shows that there is overlap between asthma and COPD.

Common Causes (COPD):
Cigarette smoking
Alpha-1 antitrypsin (AAT) deficiency
Outdoor air pollution
Long-standing asthma
Biomass and occupational exposure
a Genetic condition (symptoms; trouble breathing, jaundiced or yellow skin). Which can cause COPD at a young age and also damage lungs and liver.
alpha-1 antitrypsin (AAT) deficiency
chronic asthma
Long-standing asthma
Risk factors COPD
COPD is prevalent w/aging such as 65 years old, except for COPD brought by AAT because it is genetic and may occur in younger people.
the main component of cigarette that is mainly
causing COPD
Nicotine
Prevents the attack of neutrophil elastase
ALPHA 1 – ANTITRYPSIN
released by neutrophil, when this elastase break off from neutrophil, it destroys the bacteria and can also destroys the lungs
Neutrophil elastase
in the absence of a1-antitrypsin, the neutrophil elastase is increased, and the lungs is being continuously damaged and this can even invades the liver

a condition that features a reduced amount of the protein
AAT
GENETIC EMPHYSEMA OR Α-1 ANTIPROTEASE DEFICIENCY
May result in the early onset of emphysema
and which is inherited
autosomal codominant condition..
The importance of early identification is emphasized by the need to test (by simply sending a serum level for a1- antitrypsin testing) first-degree relatives (e.g., siblings, parents, children), by the favorable effect of primary prevention of smoking among individuals identified early, and by the availability of a specific therapy
intravenous (IV) augmentation therapy
a major structural protein that supports the alveolar walls of the lung, is normally protected by a1-antitrypsin, a protein that opposes the degradative threat of neutrophil elastase.
lung elastin
a protein contained within neutrophils that is disgorged when neutrophils are attracted to the lung during inflammation or infection.
Neutrophil elastase
individuals with established emphysema,
consideration can be given to available specific therapy

COPD may also occur without active cigarette smoking or AAT deficiency. Factors such as: may contribute to airflow obstruction that is not reversible.
1.passive smoking
2.air pollution
3.occupational exposure
4.airway hyperresponsiveness
CLINICAL SIGNS AND SYMPTOMS (COPD)
cough
phlegm production
wheezing
shortness of breath
often slow “but progressive in onset and occurs later in the course of the disease, characteristically in the late sixth or seventh decade of life.
Dyspnea
in which dyspnea begins sooner (mean age, approximately 45).
a1-antitrypsin deficiency
may show wheezing or diminished breath sounds
early
COPD
may be evident (i.e., increased anteroposterior diameter (sometimes called barrel chest),
hyperinflation
diaphragm flattening, and dimpling inward of the chest wall at the level of the diaphragm on inspiration
Hoover’s sign
is not caused by COPD alone, even if hypoxemia is present. Clubbing in a patient with COPD warrants consideration of another cause (e.g., bronchogenic cancer, bronchiectasis)
Digital clubbing
because of cor pulmonale
Bipedal edema
Other late signs of COPD include:
the use of accessory muscles of respiration,
o edema resulting from cor pulmonale,
o mental status changes caused by hypercapnia
(especially if acute, as in acute exacerbations
of chronic, severe disease),
o or asterixis (i.e., involuntary flapping of the
hands when held in an extended position, as in
“stopping traffic”).
The goal of management is to relieve the bronchoconstriction

bronchoconstriction
In managing patients with chronic, stable COPD, the following goals must guide the clinician:
-Establish the diagnosis of COPD.
– Optimize lung function.
– Maximize the patient’s ability to perform daily
activities.
– Simplify the medical treatment program as
much as possible.
– Avoid exacerbations of COPD.
– Prolong survival
In cases of emphysema and part of the lungs is severely damaged then the patient can undergo surgical procedure, which is removal of the damaged lung portion or lobe.

The major challenge facing the clinician who encounters a patient with airflow obstruction is to distinguish COPD (i.e., emphysema or chronic bronchitis or both) from
asthma.

Features that tend to favor COPD include chronic daily phlegm production, which establishes the diagnosis of chronic bronchitis; diminished vascular shadows on the chest radiograph (called hyperlucency); and a decreased diffusing capacity.

Pulmonary Disease Strategies during acute exacerbations of COPD (MEDICAL MANAGEMENT)
inhaled bronchodilators
antibiotics
corticosteroids
anti-inflammatory mediators
supplemental oxygen
especially beta-2 agonists
inhaled bronchodilators
if there’s an infection(e.g., trimethoprim-sulfamethoxazole, amoxicillin, or doxycycline)
antibiotics
to reduce inflammation and improve lung function (e.g., trimethoprim-sulfamethoxazole, amoxicillin, or doxycycline)
corticosteroids
theophylline
anti-inflammatory mediators
theophylline
anti-inflammatory mediators
to maintain arterial saturation at greater than 90%, inhaled bronchodilators, oral antibiotics, and a brief course of systemic corticosteroids
supplemental oxygen (O2)
recommended for px with COPD
Bronchodilator therapy
produce smooth muscle relaxation, resulting in improved airflow obstruction, improved
symptoms and exercise tolerance, and decrease in the frequency and severity of exacerbations, but they do not enhance survival
Bronchodilators
can improve airflow in patients with COPD, although many clinicians favor an inhaled
anticholinergic and sympathomimetic bronchodilators
first-line therapy (COPD)
anticholinergic medication (e.g., ipratropium bromide)
Controlled trials do show lessened dyspnea in methylxanthine recipients despite lack of measurable increases in airflow.18 Side effects of methylxanthines include anxiety, tremulousness, nausea, cardiac arrhythmias, and seizures. To minimize the chance of
toxicity, current recommendations suggest maintaining serum theophylline levels at 8 to 10 ug/mL.

Strategies to improve lung function in acute exacerbations of COPD generally include inhaled bronchodilators (especially (32-agonists) and systemic corticosteroids. An early randomized, controlled trial of IV methylprednisolone for patients with acute exacerbations has shown accelerated improvement in FEV1 within 72 hours.
