Title

Randomized Clinical Trial to Evaluate the efficacy of Gomutra Haritaki Rasyana with and without Virechana Karma in the Management of Kaphaj Hrudroga (Coronary Artery Disease).

Research question:

What is the efficacy of Gomutra Haritaki Rasyana, both with and without Virechana Karma, in the management of Kaphaj Hrudroga (coronary artery disease)

Hypothesis

Null hypothesis: There is no significant difference in the efficacy of Gomutra Haritaki Rasyana with Virechana Karma compared to Gomutra Haritaki Rasyana without Virechana Karma in the management of Kaphaj Hrudroga (Coronary Artery Disease).

Alternative hypothesis: There would be significant difference in the efficacy of Gomutra Haritaki Rasyana  with Virechana Karma compared to Gomutra Haritaki without Virechana Karma in the management of Kaphaj Hrudroga (Coronary Artery Disease ).

According to world health organization cardiovascular diseases are the leading cause of death globally. Coronary artery disease (CAD) also known as atherosclerotic heart disease is the most common type of heart disease and a frequent cause of cardiac events. The World Health Organization reported that, In 2022, there were 315 million people with CAD globally, with an age-standardized prevalence of 3,605 per 100,000[1]. In urban India, the prevalence of CAD has increased from 1.1% to about 7.5% over the last three decades. In rural India, the prevalence has increased from 2.1% to 3.7%[2]. This disease has been proved to be the major cause of death in both the developed and developing countries. Lifestyle, environmental factors, and genetic factors pose as risk factors for the development of cardiovascular disease. The risk factors of CAD include diabetes mellitus, hypertension, smoking, hyperlipidemia, obesity, homocystinuria, and psychosocial stress. The implementation and maintenance of healthy lifestyle behaviours are considered the rate limiting step in cardiovascular disease prevention. The epidemiological transition views the period of mid nineteen century as the period of transition from infectious to non infectious disease and increase in lifestyle diseases such as cardiovascular diseases.Coronary artery disease (CAD) presents with a wide range of symptoms, reflecting its impact on multiple organ systems. The primary symptoms of CAD often include fatigue and shortness of breath, which arise from the heart’s decreased ability to pump blood effectively. As the disease progresses, patients may experience orthopnea, or difficulty breathing while lying flat, and paroxysmal nocturnal dyspnea (PND), characterized by sudden episodes of breathlessness at night.

Effective management of coronary artery disease requires a holistic approach addressing primary cardiac issues and secondary effects on other organs. This includes lifestyle changes, medications, and interventions, alongside monitoring for complications like kidney dysfunction and cognitive decline. A multidisciplinary team and patient education are essential for optimal outcomes.

Cardiovascular disorders are discussed under Hrudroga in ayurveda. As ayurveda is recognized as a foremost life science and describes way to prevent and manage lifestyle disorders, the world is being attracted towards its potential. Ayurveda provides better solution in the form of Hrudya regime which includes proper dietary management, lifestyle advices, Panchakarma like detoxification and biopurification procedures, medicaments and rejuvenation therapy.

Need of the study

Despite important advancements in the pharmacotherapy of coronary artery disease (CAD), the actual percent reduction in mortality associated with the use of modern pharmacological agents has been relatively unpretentious. Moreover, the available pharmacological agents are also not free from various adverse effects. In the current epidemiological shift of diseases in a global perspective, where the life style diseases, degenerative diseases and mutagenic diseases are over extended, for which the current practises in medicines are proving to be inadequate and thus the need for an evidence-based approach of medicine is needed. Hence there is an immense requirement of certain Ayurvedic drugs which can increase efficiency and performance of compromised heart for healthy living in a natural way with least possible adverse effects. Ayurveda is having such prepatent ability for correcting that inadequacy in managing these diseases, which can be managed and prevented with proper assessment and intervention.

     Regular diet with Dhanyaka- Shunthi Jala (water processed with Coriander and ginger powder).

2.     Snehapana

     Luke warm water whole day as and when required.

      Moong dal soup – Soup of green gram.

      Roti + boiled green vegetables with spices. Whenever required.

                 The above food item should be taken only when patient feel excessive hunger.

3.     Abhyanga- Svedana(External massage and sudation):

      Khichadi (Polenta)- Prepared by moong dal (green gram) plus rice plus ginger powder plus turmeric powder and Saindhavalavan.

      Moong dal soup – Soup of green gram with spices – Pepper, ginger etc.

      Roti and  boiled green vegetables with spices.

4.     During Virechana-  Virechana should be given empty stomach and during purgation hot water is allowed to drink. After completion of Virechana diet is planned according to the number of Vega (number of stool pass).

5.     After Virechana: Protocol of diet after Virechana is very specifically defined in Ayurveda and termed as Samsarjana Krama. This dietary regulation advocates the restoration of normal diet in sequential manner starting from very light liquid diet. The dietary module given after Virechana is as followed-

M=morning, E=evening; Pravara Shuddhi= Nu. of stool> 20; Madhyam Suddhi- Nu. of stool> 10; Avara Suddhi- Nu. of stool < 10

Shali – The official botanical name is Oryza sativa but is commonly referred to in English as Asian rice, Paddy or simply (rice). 

    Peya- Thin gruel, Vilepi= Thick gruel, Akrut Yusha= Unprocessed green gram soup, Krut Yusha isProcessed green gram soup, Krut Mamsa rasa= Processed meat juice, Akruta mamsa rasa- Unprocessed meat juice.

      Manda, Peya, Vilepi, Yavagu, Odana in Samsarjana krama are prepared by using rice.

      Manda is very thin gruel prepared by boiling rice in water, the watery portion is manda.

      Peya is liquid rice gruel prepared by boiling rice until it becomes very soft and thin.

      Vilepi is thick gruel with more of boiled rice in it.

      Yavagu is semi solid food with much rice and very little of fluid in it.

      According to Sharangdhara four Pala rice (1 Pal= 48g) boiled in 14 times water, the watery portion is manda and the thick rice is madhura and laghu that is odana. According to Shushrut, Odan is cooked rice prepared from washed rice, dirt free rice, pleasing to mind, pleasant odour, it should be well cooked, hot or warm, drained off fluid, vishada (non-slimy), easily digestible. That prepared from unwashed rice, not drained off its fluid, not well boiled, and which has become cold is hard for digestion. That prepared from bhrushta tandula (fried rice) are laghu sugandhi, migitates kapha.

      Yusha According to Sharangdhara, 1 Pal dravya kalka (48 g of paste) , sunthi and pippali half karsha and drava bhaga one prastha should be taken and boiled till it reduce to half the quantity of drava bhaga, that is yusha.

      Yusha is prepared by Shimbi dhanya (pulses) like mudga (green gram), masoor (red lentils), chana (split Bengal gram), kulattha (horse gram), etc. But preferably for Samsarjana krama mudga is used. There are two types of yusha- akrut yusha (unprocessed) krut yusha (processed with spices, oil and salt).

      According to Sushruta, akrut yusha (unprocessed) is liquid diet which is not added with sneha (oil) lavana (salt) and katu rasa and krut yusha is liquid diet which is medicated with sneha lavanaand katu rasa (green gram soup processed with oil, salt and spices).

Medication(s)/treatment(s) permitted (including rescue medication) and not permitted before and/or during the trial.

      No concomitant medicine or treatment will be allowed during trial period except the rescue medicine if any adverse reaction appears.

STATISTICAL METHODS

The data will be presented in the form of Descriptive statistics such as Mean SD, SEM or Range, etc., and Median with 25 and 75 Percentile, Qualitative variables will be presented as counts and percentages.

Data sets-Efficacy assessment as per protocol set and safety assessment with Intent to treat set. The data generated would be subjected to a normality test with the Shapiro-Wilk test. If the normality test is passed, a parametric test would be employed otherwise non-parametric test is employed.

For objective data, the paired t test will be employed to assess before and after treatment differences within the groups and Repeated measures of ANOVA(R-M Anova) will be employed to assess the differences between the groups. This will apply to hematological parameters and calcium scoring during the trial.

For subjective data, the Wilcoxon signed rank test will be employed to assess before and after treatment differences within the groups, Mann Whitney test will be employed for assessing the difference between the groups.

The changes observed with a p value less than 0.05 will be considered significant and less than 0.001 to be highly significant.

IBM SPSS Statistics for Windows, version 26 will be used for the statistical analysis. Also, the standardized effect size will be calculated to ascertain the significant difference observed in the clinical evaluation.
