Cardio-/Cerebrovascular Disease, a common and frequently-incurring disease happening on the aged people, is one of most dangerous diseases to human body. Although there are certain therapeutic effects by taking drugs, high-pressure oxygen and ECP treatment (external counter pulsation), such treatments are not satisfying for prevention of this disease and patients’ recovery. Cardio-/Cerebrovascular therapeutic instrument series, produced by King Tontown Medical Instrument Co., Ltd. with the adoption of high-strength & specific alternating electromagnetic wave, give a better effects for the treatment of this disease, and are well accepted by users both at home and abroad. Our department has used this instrument on 30 cases from July to December 1995 with a better result. Therefore, we herby report it as below:
Materials and Methods
I. Choice of Cases:
According to WHO's diagnose standards for coronary heart disease and angina pectoris, we chose 24 patients who suffered the attack of angina pectoris for more than 2 times/days with ST-T change, or whose flat floor test result showed negative, including 14 male patients and 10 female patients aged from 48 to 77 years old averaging 62.6 years old. The duration of angina pectoris was from 1 to 10 years. 6 cases suffered from the angina pectoris with high blood pressure and 6 cases got cerebrovascular accident. All are male aged from 56 to 60 years old, including 4 cases of cerebral infarction, 1 case of left spastic paralysis after brain trauma and 1 case of Parkinson’s disease.
II. Therapeutic Methods
Apply the Cardio-/Cerebrovascular Therapeutic Instrument of King Tontown Medical Instrument Co., Ltd., and input 220V power with 50Hz frequency and output the alternating electromagnetic wave. The patient needs to repose on a special insulated therapeutic bed, 1 hour per time and 1 time per day. One course of treatment is for 15-30 days, and if necessary, the patient could stop treatment for one week. A consecutive treatment may be required for 2～3 courses.
The patients who suffering angina pectoris were required to stop taking anti-angina pectoris drugs, but if necessary, could take nitroglycerin. Cerebrovascular accident patients were required only to take nutritious medicine for brain cells and stop taking blood vessel dilatation medicine.
III. Observation Guide:
1. Angina pectoris patients: increase/decrease of angina pectoris attack, change of heart rhythm and blood pressure, change of ST-T.
2. Cerebrovascular accident patients: subjective symptom, language, change of muscle strength and behavior.
Before treatment, the measuring for the change of the blood fat, BUN and blood sugar for above-mentioned patients was made, and few of them need to have microelements test.
V. Criteria for Treatment Effect (Provision)
1. Patients of angina pectoris:
① Apparent Effects: subjective symptom improved, angina pectoris attacks decreased and disappeared, and change of ST-T became normal.
② Turn Better: subjective symptom improved, angina pectoris attacks decreased to less than 2 time per day; ST-T change turned better.
③ Ineffective: above effects were not achieved.
2. Patients of cerebrovascular accident:
①Apparent Effects: symptoms improved and hemiplegia disappeared.
②Effective: symptoms improved, muscle strength increased and better actions.
③ Ineffective: No change.

From Table 1, we observed 30 cases of Cardio-/Cerebrovascular patients with a total effectiveness of 93.3%. It was much better to relieve the angina by using this instrument. With the increase of treatment, the angina pectoris attacks decreased and even disappeared, and patients with Apparent Effect and patients with Effect took up 50% respectively. The effectiveness for cerebral infarction was 75%. There was no effectiveness on arteriosclerosis and Parkinson’s disease patients after one course of treatment.

From Table 2, there were 24 cases whose ECG ST-T changed and improved after one course of treatment, including 7 patients' ST-T went normal (29.2%), 8 patients turned better (33.3%) and 9 patients failed (37.5%), and the total effectiveness was 62.5%. The ECG change of Patients with pathologic changes of cerebrovascular disease was blocked at the fist half course of treatment. One case was found negative in atrial fibrillation and flat floor tests respectively with no obvious improvement after treatment.
III. Change of Blood Pressure before and after Treatment
Among 30 cases of this group, there were 22 cases with normal blood pressure and a little change after treatment, and there were 2 cases with low blood pressure-12.0 kpa/8.0 Kpa (90/60mmHg) whose blood pressure increased to 14/8.66Kpa(105/65mmHg) after treatment. This instrument has function of adjusting blood pressure. There were 6 case with angina and high blood pressure whose blood pressure averaged 21.6±1.4/12.7±1.2kpa(162.4±10.5/95.6±9.3mmHg) before treatment, while after treatment their blood pressure reduced to 18.62±14.5/11.3±1.12kpa(140±10.9/85±8.4mmHg), including systolic pressure dropped greater than 1.33～2.67kpa（10～20mmHg), diastolic pressure dropped by 0.67～1.33kpa(5～10mmHg) and P value＜0.01. There was great difference before and after treatment showing that “Cardio-/Cerebrovascular Therapeutic Instrument” has certain effect for relief of blood pressure.

IV. Heart Rate
Before treatment, the averaged heart rate is 78 beats/minute (bpm), and 74 bpm after treatment. Therefore there was little change before and after treatment and no meaning to make statistics.
V. Biochemical Change
There was little change in blood sugar, blood fat and BUN, so it is no statistic meaning. 6 patients had the microelement test, including that two persons were found decrease of iron and copper elements after treatment. Due to the lack of patients, we did not make the statistics.
VI. Side Effect
The treated patients had slight sense of body shaking when starting the instrument, but the shaking disappeared with time passed. One case was found excited after 6 treatments with bad sleeping. He need take sleeping pills.
Discussion
Cardio-/Cerebrovascular Therapeutic Instrument” works via the alternating electromagnetic field produced by itself. The effect by Electromagnetic filed can dilatate the blood capillary and speed blood flow (1); Meanwhile, Electromagnetic field can stimulate circulation to end stasis and improve the bloods circulation (2). Therefore, this instrument can improve the blood supply of coronary arteries and reduce the lacking of blood in cardiac muscle to relieve the angina. In this group, the relief of angina pectoris reached 100%, the Turn-better rate of ECG reached 62.5% and 29.2 for the Apparent Effective Rate. It shows that this instrument is a good choice to cure the angina pectoris of coronary heart disease.
“Cardio-/Cerebrovascular Therapeutic Instrument” works via electromagnetic effect, heat effect and micro-movement to improve the blood supply to the brain for the patients with cerebrovascular accident. The experiments prove that high-strength & specific alternating electromagnetic field can speed the reproduction of medullary sheath, eliminate the nerve hydrops and improve the repairing of mechanical injury of peripheral nerve (3). In this paper, there were 4 cases of cerebral infarction and 1 case of brain trauma who showed poor effect after taking western and Chinese traditional medicines, acupuncture and high-pressure oxygen. They felt that the muscle is eased and relieved, the muscle strength increased, and they could speak clearly with more words and did better in actions after using this Cardio-/Cerebrovascular Therapeutic Instrument. In this group, there was a male patient aged 62 years old with high blood pressure and cerebral infarction who had hemiplegia on the right side for half a month. He had received many treatments by taking Xueshuantong, cerebrolysin, and citicoline, acupuncture and high-pressure oxygen, but not improved. After 15 times of treatment by using this instrument, the patient could speak clearly and smoothly and walk without the crutch.
“Cardio-/Cerebrovascular Therapeutic Instrument” also can adjust the cerebral cortex and restrain the excitement and restore the balance. Many patients felt that they had a better sleeping, less dreams with no headache after using this instrument. Through observation on this group, the instrument has the functions of adjusting the tension of blood vessels and expanding blood vessels to reduce the blood pressure. There were 6 cases with high blood pressure and angina pectoris of coronary heart disease, among whom there were 4 patients began to reduce the blood pressure to normal and stopped taking pressure-relief drugs, and 2 patients showed signs of pressure relief. Normally, the blood pressure can be reduced to that the systolic pressure reduced by 1.33-2.67Kpa (10-20mHg) and the diastolic pressure dropped down by 0.67-1.3Kpa (5-10mmHg). Therefore, this instrument has effect of pressure relief. As the therapeutic effect is related with the course of illness and treatment, the longer course of illness, the poorer effect of therapy, and vice versa. So if the patients carry out medical treatment at the early stage, it is good for their recovery. Generally, it is better to use this instrument for 30 days (times) and for strengthening the effect, the patients can take the second course of treatment after 3-7 days of rest.
Cardio-/Cerebrovascular Therapeutic Instrument produced by King Tontown Company is featured with fast work, good medical effect and no side effects. As an adjutant method to cardio-/cerebrovascular disease, this instrument is easy and safe to operate, and is worth being promoted for application.
