Pilot project committee of Chinese adult dyslipidemia health management service and Editorial Committee of Guidelines for the management of cardiovascular diseases in community populations (The Trial)

<Chinese cardiovascular disease report 2015> indicated that the prevalence of cardiovascular disease is on the rise in china.[1] In 2014, the death rate of cardiovascular diseases in rural and urban areas was the first. Therefore, it is particularly important and urgent for screening and prevention of major cardiovascular disease risk factors of hypertension, dyslipidemia, overweight/obesity, diabetes, smoking, and major cardiovascular diseases (coronary heart disease and stroke) in the community.

  1. Major risk factors

  2. 1.1 Hypertension

    1.1.1 The objective of prevention and treatment of hypertension

    1. Screening population: Individuals who have headache, dizziness, and/or have the risk factors of hypertension (high-sodium and low-potassium diet, overweight and obesity, drinking, mental stress, lack of exercise, as well as those 35 years of age or older, and have family history of premature hypertension and lack of sleep[2],[3])
    2. Hypertension population: The blood pressure (BP) is ≥140/90 mmHg at different dates and different time of consulting room measuring BP more than 3 times; or 24 h ambulatory BP mean value is ≥130/80 mmHg, ≥135/85 (mmHg) at the day (awake), ≥120/70 mmHg during night sleep.[4]

    1.1.2 Community management of hypertension

    1. To establish the community hypertension electronic health record and carry out the education of therapeutic lifestyle [Appendices 1 and 2]
    2. The target BP: BP <140/90 mmHg for individuals <65 years; BP <150/90 mmHg for individuals >65 years[3]
    3. Selection of antihypertensive drugs: Calcium channel blockers, angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor antagonist (ARB), diuretics, beta blockers (BBs), and fixed compound preparation. The specific use of drugs and drug safety [Appendix 3]
    4. The risk stratification, regular monitoring of BP, standardized follow-up [Appendices 4 and 5].

    1.1.3 Indication of referral to higher level hospital

    1. With new-onset heart disease or new onset stroke
    2. Sustained BP ≥ 180/110 mmHg or hypertensive crisis
    3. Suspected secondary hypertension
    4. Children, adolescents, pregnant women, and lactating women
    5. Refractory hypertension (after a reasonable combination of lifestyle modification and diuretics including diuretics, at least 3 antihypertensive drugs were administered, and the BP was not up to standard)
    6. There cannot be explained or difficult to deal with adverse reactions after taking antihypertensive drugs, as shown in Appendix 3
    7. Hypertension associated with multiple risk factors or target organ damage and difficult to deal with.

    1.1.4 Evaluation index of hypertension community management

    1. Hypertension screening rate = number of BP screening/community resident population × 100% in over 18 years
    2. Ambulatory BP utilization = ambulatory BP utilization/number of hypertensive patients with electronic records × 100% in hypertension management population
    3. The coincidence rate of referral index of patients with hypertension management = the number of patients with referral indications/hypertension referral cases × 100%.

    1.2 Dyslipidemia

    1.2.1 The objective of prevention and treatment of dyslipidemia. Community physicians assessed dyslipidemia among people in the district according to [Table 1]. All patients diagnosed with atherosclerotic cardiovascular disease (ASCVD) and those whose blood lipids were not up to standard were all the subjects of prevention and treatment of dyslipidemia. Target of intervention of dyslipidemia is shown in [Table 1].
    Table 1: Targets of dyslipidemia intervention for combined clinical disease or risk factors

    1.2.2 Community management of dyslipidemia. Community doctors divide patients with dyslipidemia into different management levels and implement classified management as well as the annual evaluation and adjustment of management level for patients within the jurisdiction according to the goal of lipid lowering.

    For low-density lipoprotein cholesterol (LDL-C) as the intervention target, statins are preferred. Statin therapy should be initiated for patients with clinically diagnosed ASCVD regardless of their baseline LDL-C levels and if LDL-C is <1.8 mmol/L, with more than 50% decline as a therapeutic target. Statins of different dosages and dosages descending LDL-C amplitude reference [Table 2].[5]
    Table 2: Cholesterol lowering by statins

    Moderate or high intensity statin therapy should be selected unless the patient cannot be tolerated. If LDL-C failed to reach the target after statin therapy, one can choose ezetimibe combination (10 mg × 1/day).[6] For pure triglycerides (≥G e mmol/L), fibrates or nicotinic acid drugs should be the first choice to prevent the occurrence of acute pancreatitis.[7]

    1.2.3 Indication of referral to higher level hospital

    1. After 3–6 months of strict lifestyle intervention and standard drug treatment, LDL-C has not yet reached the target value
    2. Severe adverse reactions occurred when taking lipid regulating drugs
    3. Untreated LDL-C > 4.9 mmol/L and suspected familial hypercholesterolemia
    4. Secondary dyslipidemia.

    1.2.4 Evaluation indexes of community management of dyslipidemia

    1. Dyslipidemia detection rate = dyslipidemia number/number of screening × 100%
    2. The treatment rate of dyslipidemia patients = the number of treatment cases/the number of patients with dyslipidemia × 100%
    3. The coincidence rate of referral index of patients with dyslipidemia = the number of referral cases/dyslipidemia × 100%.

    1.3 Overweight and obesity

    1.3.1 The objective of prevention and control. Overweight and obesity were assessed with body mass index (BMI), BMI = weight (kg)/height2 (m2). Overweight: BMI 24–27.9 kg/m2; obesity: BMI ≥28 kg/m2. If the individual muscle is highly developed, BMI is not suitable as a diagnostic standard for.[8]

    1.3.2 Community management

    1. Control target:[8] weight reduction at least 5%–10% or BMI <25 kg/m2
    2. To carry out the treatment of lifestyle education, regular monitoring of weight waist and circumference
    3. Drug therapy for weight loss: Under the guidance of a specialist, you can consider orlistat and other weight loss drugs.

    1.3.3 Indication of referral to higher level hospital

    1. Secondary obesity was suspected, especially in children and adolescents
    2. Combined with heart disease, new stroke, diabetes, hypertension, and sleep apnea–hypopnea syndrome
    3. BMI ≥32 kg/m2, lifestyle, and drug intervention were ineffective.

    1.3.4 Assessment index of overweight community management

    1. Overweight and obesity detection rate = overweight or obesity number/number of visits × 100%
    2. Receive health education with weight control at least once a year.

      1. The typical symptoms of diabetes, polydipsia, polyuria, polyphagia, and weight loss, random plasma glucose detection ≥11.1 mmol/L
      2. Fasting blood glucose ≥7 mmol/L (not on the same day)
      3. Hours after glucose load, blood glucose level ≥11.1 mmol/L (2 time not on the same day)
      4. Fasting blood glucose ≥7 mmol/L and 1 time glucose ≥11.1 mmol/L 2 h after glucose load.

    2. Patients with impaired glucose regulation: Impaired fasting glucose refers to the fasting blood glucose was 6.1–6.9 mmol/L, 2 h postprandial blood glucose <7.8 mmol/L. Impaired glucose tolerance refers to the 2 h blood glucose after glucose load is 7.8–11.1 mmol/L and fasting blood glucose <6.1 mmol/L.

    1.4.2 Community management of diabetes prevention and control

    1. The blood glucose control objectives: Most nonpregnant adult patients with type 2 diabetes fasting blood glucose level is 4.4–7 mmol/L, 2 h postprandial blood glucose <10 mmol/L, glycosylated hemoglobin (HbA1c 7.0%).[10] To formulate individual goals based on the patient's age, course of disease, life expectancy, complications, the severity of the disease and so on
    2. To establish community population diabetes electronic health records and to carry out education and intervention on therapeutic lifestyle of diabetes mellitus, regular monitoring of blood glucose and standardized follow-up
    3. The principle of choosing hypoglycemic drugs:

      1. Patients with type 1 diabetes mellitus should be treated with insulin or insulin analogs and to avoid hypoglycemia (blood glucose level is ≥3.9 mmol/L).
      2. The type 2 diabetes: Individual control objectives and treatment options are used; the current commonly used oral hypoglycemic drugs including metformin and insulin secretagogues, alpha glucosidase inhibitors and two dipeptidyl peptidase-4 inhibitor, thiazolidine two ketones, can be used when necessary insulin or insulin analogs treatment.

    1.4.3 Indication of referral to higher level hospital

    2.2 Stroke

    2.2.1 The subjects of stroke prevention and control

    1. The subjects have been diagnosed with stroke (including transient ischemic attack [TIA])
    2. Stroke should be considered if the patient suddenly shows any of the following symptoms[16] [Appendix 6]:

      1. Weakness or numbness of one limb (with or without facial)
      2. Facial numbness or angular deviation on one side
      3. Unclear speech or understanding of language difficulties
      4. Eyes gaze sideways
      5. The unilateral or bilateral visual loss or fuzzy
      6. The dizziness and vomiting
      7. Severe headache, vomiting, previously rare
      8. The disturbance of consciousness and/or twitch
      9. Risk factors: Hypertension, dyslipidemia, diabetes mellitus, hyperhomocysteinemia, smoking, atrial fibrillation, overweight or obesity, lack of exercise, family history of stroke.[17]

    2.2.2 Community management of stroke Target: The primary, secondary, and third prevention (rehabilitation) of stroke and reduce the incidence and recurrence rate of stroke. Treatment measures

    1. Primary prevention

      1. The control of risk factors: Control of BP (<65 years, BP <140/90 mmHg; ≥65 years, BP < 150/90 mmHg). Blood lipid regulation: long-term statin therapy (LDL-C <1.8 mmol/L or drop over 50%).[18] Blood glucose control (HbA1c <7%). Patients with hypertension complicated with hyperhomocysteinemia (>10 mmol/L): folic acid supplementation is recommended
      2. Antiplatelet aggregation therapy: Benefits and risk assessments are needed, and medication is appropriate
      3. Anticoagulation therapy: Atrial fibrillation in rheumatic valvular heart disease is a definite indication of warfarin anticoagulation. Nonvalvular atrial fibrillation patients with CHA2DS2-VASc score ≥2 points to warfarin anticoagulation,[19] international normalized ratio (INR) must be monitored (target value: 2–3),[20] The new oral anticoagulants, such as dabigatran, Shaaban, and Shaaban, do not need to monitor INR, so they can be used.

    2. Secondary prevention

      1. Control risk factors
      2. TIA and light stroke treatment.[21] TIA and light stroke are serious and urgent intervention stroke warning events
      3. Patients with noncardiogenic ischemic stroke may receive oral antiplatelet therapy such as aspirin and/or clopidogrel
      4. Ischemic stroke of cardiogenic (atrial fibrillation): Anticoagulant therapy is the first choice.

    3. Third prevention: Rehabilitation therapy in community (acupuncture, physiotherapy, functional recovery training)[22] Health education for stroke patients with therapeutic lifestyle, regular review, standardized follow-up.

    2.2.3 Indication of referral to higher level hospital:

    1. Patients with suspected stroke (include TIA)
    2. Patients with previous history of stroke and poor control of these risk factors
    3. Patients who took warfarin anticoagulation, INR <2 or INR >3
    4. Patients with atrial fibrillation and/or rheumatic valvular disease who cannot be treated with anticoagulation.

    2.2.4 Treatment before referral:

    1. Stroke patients need immediate referral to a hospital with thrombolytic qualification
    2. Keep the vital signs stable as much as possible
    3. Timely delivery of patient information before referral.

    2.2.5 Evaluation index of stroke prevention and treatment

    1. The referral rate of the first diagnosed stroke patients = the number of referral cases in the first diagnosis stroke patients/the number of patients with first diagnosed stroke × 100%
    2. Standardized treatment rate of stroke (include antiplatelet aggregation, statin therapy, BP control) = number of patients with standardized treatment of stroke/number of patients diagnosed with stroke × 100%.
