Modified Canadian Cardiovascular Society grading of angina pectoris.

Modified Canadian Cardiovascular Society

grading of angina pectoris

Canadian Cardiovascular Society grading of angina pectoris contain only 4 grades and Class 0 is not an official part of the CCS functional classification of angina pectoris, however it has been mentioned in several sources, referring to myocardial ischemia without symptoms.

Grade 0

Asymptomatic Angina

Mild myocardial ischemia with no symptoms.

Grade I

Angina only with strenuous exertion

Angina with strenuous or rapid or prolonged exertion at work or recreation (Ordinary physical activity does not cause angina, such as walking and climbing stairs).

Grade II

Angina with moderate exertion

Slight limitation of ordinary activities when they are performed rapidly, after meals, in cold, in wind, under emotional stress, during the first few hours after waking up, but also walking uphill, climbing more than one flight of ordinary stairs at a normal pace and in normal conditions.

Grade III

Angina with mild exertion

Having difficulties walking one or two blocks or climbing one flight of stairs at normal pace and conditions.

Grade IV

Angina at rest

No exertion needed to trigger angina.

(CXR demonstrating Mesothelioma of left lower lung)

  • Pleura. (is the most common form of the disease, accounting for roughly 70% of cases).
  • Peritoneum.
  • The pericardium (1).
  • The tunica vaginalis.

- Metabolic syndrome (Syndrome X).

 Metabolic syndrome
-Def :- It is a combination of medical disorders that increase the risk of developing cardiovascular disease and diabetes (1).

-Synonyms :-syndrome X, insulin resistance syndrome, Reaven's syndrome or dysmetabolic syndrome.

 
metabolic syndrome

- How is the metabolic syndrome diagnosed or defined?
The metabolic syndrome be identified by presence of three or more of these components:
  • Elevated waist /hip ratio (i.e Abdominal obesity).
  • Elevated triglycerides:Equal to or greater than 150 mg/dL, or specific treatment for this
    lipid abnormality.
  • Reduced HDL or specific treatment for this lipid abnormality.
  • Elevated blood pressure or treatment of previously diagnosed hypertension.
  • Elevated fasting glucose levels or previously diagnosed type 2 diabetes.
-Prevention:-  life style modification which is considered the first line of prevention.
  • Increased physical activity e.g walking 30 minutes every day (2).
  • Healthy, reduced calorie diet (3).

- Pickwickian syndrome.

Pickwickian syndrome

-Def :- It is a condition in which severely overweight people fail to breathe rapidly enough or deeply enough, resulting in low blood oxygen levels and high blood carbon dioxide (CO2) levels.

-Synonyms:- Obesity hypoventilation syndrome(OHS).
-In 1836, Charles Dickens drew in his novel "The posthumous paper of the Pickwick Club" what would be, certainly, the best characterization of an obese subject with respiratory disorders(1).

- Integrated Management of Childhood Illness (Imci).

- Def:-
An integrated approach to child health which focuses on the well being of whole child.


- Aims (Broad goals-الأهداف العامة):-
  • Reduce death, illness and disability
  • Promote improved growth and development among children under five years of age.
  • Includes both preventive and curative elements implemented by families,communities and health facilities.
-Objectives(الأهداف الصغيرة-underlying goals):-

1- In Health facilities,IMCI strategy promotes:-
  • The accurate diagnosis of childhood illnesses in outpatient clinics.
  • Appropriate combined treatment of all major illnesses.
  • Improving skills of PHC staff.
  • Speeding up the referral of severely ill children.
2- In the home setting,IMCI strategy promotes:-
  • Appropriate care seeking behaviours
  • Improved nutrition and preventative care.
  • Correct implementation of prescribed care/and drugs.
- Why is IMCI better than single-condition approaches?
  • Children brought for medical treatment in the developing world are often suffering from more than one condition, making a single diagnosis impossible.
  • IMCI ensures the combined treatment of the major childhood illnesses, emphasizing prevention of disease through immunization and improved nutrition.
-Rationale of IMCI in developing countries:-

1-More than10million deaths/year among children under 5 years of age in developing countries.

2-70% of these deaths are due to just 5 preventable and treatable
conditions
(pneumonia,diarrhea
malaria,measles and malnutrition).


3-Surveys show that many sick children aren't properly treated by healthcare providers as their parents are poorly advised.

4-In developing countries diagnostic aids (Radiology or lab) are minimal or absent.

5-In developing countries drugs and equipment are limited.

6-These limitations leave doctors helpless,they often rely on history,signs and symptoms to determine the management with least cost.


- Components :-
The strategy includes three main components:-
  • Improving case management skills of health-care staff(health-worker component).
  • Improving overall health systems(health-service component).
  • Improving family and community health practices(community component).
-The department responsible for IMCI in WHO is called "Child and adolescent health department"(CAH) here.


-Benefits of Integrated Management of Childhood Illness (IMCI)(3):-
  • Addresses major child health problems by addressing the most important causes of childhood death and illness.
  • Responds to demand – Every day millions of parents take their sick children to hospitals and health centres,pharmacists and community health care providers. At least three out of four of these children are suffering from one of the five conditions that are the focus of IMCI.
  • Promotes prevention as well as cure .
  • Is cost-effective – Investing in Health ranked IMCI among the 10 most cost-effective interventions in both low- and middle-income countries.
  • Promotes cost saving – Inappropriate management of childhood illness wastes scarce resources. Although increased investment will be needed initially for training and reorganization, the IMCI strategy will result in cost savings.
  • Improves equity – Nearly all children in the developed world have ready access to simple and affordable preventive and curative care which protects them from death due to ARI, diarrhoea, measles, malaria and malnutrition. Millions of children in the developing world, however, do not have access to this same life-savingcare. The IMCI strategy addresses this inequity in global health care.
-Implementation of IMCI:-
(How does IMCI achieve these goals?)
1-Adopting this strategy in the national health policy.
2-Adapting the standard IMCI clinical guidelines to the country's needs,Available drugs,policies,and to local foods.
3-Upgrading care in PHC units by training staff in new methods of management of children.
4-Implementation of the concept of the essential drug list.
5-strengthening the referral system.
6-Implementation of IMCI is done in conjugation with other health strategies (e.g Roll back malaria,Nutrition,EPI,IMPAC).
