Chennai: In-service candidates taking admission to the super-speciality courses in Tamil Nadu will have to serve the Government till superannuation or pay Rs 50,00,000 as bond penalty.

As per the latest prospectus, issued by the Directorate of Medical Education and Research (DMER), Chennai, at the time of admission to the super-speciality courses in the government medical colleges in Tamil Nadu, the doctors will have to execute a bond for Rs 50 lakh as a security amount with an undertaking specifying their commitment to work for the Government till their retirement.

They will also have to submit three sureties along with the bond. Among these, two sureties should be from permanent Government employees in the same or higher rank than the candidate, and one surety should be from the spouse/parent of the candidate.

However, the DMER specified that the bond will become infructuous if the in-service candidates serve the Government of Tamil Nadu after the completion of the course until superannuation.

“All Service Candidates of Tamil Nadu shall execute a bond for a sum of ₹50,00,000/- (Rupees fifty lakh only) as security amount with the under taking that they will serve the Government of Tamil Nadu till Superannuation with three sureties. Two sureties should be from permanent Government employees in the same or higher rank than the candidate. One surety should be from the spouse / parent of the candidate. PAN numbers of the sureties should be furnished…. The bond will become infructuous if the service candidates serve the Government of Tamil Nadu after the completion of the Course until superannuation,” read the prospectus.

In the prospectus, the DMER further mentioned that the Government of Tamil Nadu is offering Super Speciality courses through its Medical Colleges/Hospitals and the Tamil Nadu Dr. M.G.R Medical University/Specialised institutes and stated:

“The Government spends a large amount of money to impart Medical Education including Super Speciality Medical Education. It levies nominal fees and at the same time provides stipend to Private candidates and salary to Service candidates. It is natural that the Government desires to ensure that these seats are not wasted. Further, the Government looks forward to these Doctors who have undergone Post-Graduate training to serve the poor and the needy of this country at large and this State in particular. The public have the right to expect the Specialists to utilize the skills they acquired during their training for the benefit of the sick, the poor and the needy. To ensure that the services of trained Post Graduate Doctors are made available, an Undertaking is obtained from them at the time of their admission. It is sincerely believed that this will discourage an attitude of not paying attention to those poor people at whose expense they have been educated,” the prospectus stated.

Medical Dialogues had earlier reported that recently Tamil Nadu (TN Health) invited online applications from eligible candidates for admission into the Super Speciality courses in TN Government Medical Colleges only for in-service candidates for the 2024 session. In this regard, TN Health released a prospectus detailing the important details such as eligibility criteria, procedure for filling & submission of application, counselling procedure, tuition fee, method of selection, admission, etc.

Cardiovascular diseases (CVD) account for 24.8% of all deaths in India, with an age-standardized death rate of 272 per 100,000-higher than the global average. (1) Indians develop CVD nearly a decade earlier than Western populations, with 62% of deaths occurring prematurely. Key cardiometabolic risk factors-hypertension, diabetes, and obesity-have driven a 2.3-fold rise in ischemic heart disease and stroke. (2)

CVD complications are also evident in acute settings: 20% of adults hospitalized with pneumococcal pneumonia experience heart failure, arrhythmia, or myocardial infarction. (3) Nearly 12% of patients developed heart failure within a decade of hospitalization, highlighting the prolonged cardiovascular impact of systemic infections such as pneumonia. (4)

Cardiopulmonary Overlap and Risk of Respiratory Infections in CVD

Cardiovascular and respiratory diseases frequently coexist due to shared risk factors such as smoking and systemic inflammation.(5) Symptom overlap is common-cardiac conditions like heart failure may present with respiratory features (e.g., cardiac asthma), while chronic lung disease increases right ventricular strain, predisposing to CHF. (6)

The risk intensifies with respiratory infections. Patients with cardiovascular disease—including CHF, valvular disease, and congenital heart disease—face a 3.3-fold higher risk of community-acquired pneumonia (CAP) and a 9.9-fold higher risk of invasive pneumococcal disease (IPD). (7) During IPD, Streptococcus pneumoniae translocate across the vascular endothelium and invades the myocardium, directly killing cardiomyocytes and immune cells. (8) This results in acute myocardial injury and can lead to long-term cardiac dysfunction, compounding the cardiovascular burden in affected patients. (9)

Clinical trials such as PARADIGM-HF and PARAGON-HF have demonstrated a significant incidence of pneumonia among heart failure patients. Pneumonia occurred in 6.3% (29 per 1,000 patient-years) of PARADIGM-HF patients and 10.6% (39 per 1,000 patient-years) of PARAGON-HF participants. The onset of pneumonia in these patients substantially increased the risk of adverse outcomes. (10)

Importance of Preventing Pneumococcal Disease in Cardiovascular Disease Patients

Preventing pneumococcal disease is vital for CVD patients, particularly those with heart failure and CAD, as they are more vulnerable to bacterial infections like pneumonia and other respiratory illnesses. These infections can trigger cardiac decompensation, increasing hospitalizations and mortality. Vaccination against pneumococcus lowers the risk of respiratory infections, heart failure exacerbations, and cardiovascular events. Given weakened immunity and constant exposure to airborne pathogens, vaccination helps stabilize heart function, reduce inflammation, and ease healthcare burdens. (11)

Pneumococcal Vaccination in Cardiovascular Diseases – When to Consider?

Table 1 provides adult vaccine recommendations for heart failure and related high-risk conditions per the API(Association of Physicians of India) 2024 guidelines.

Table 1: Vaccination Recommendations for High-Risk Cardiac and Chronic Conditions

Vaccination should be considered a priority for individuals with CVD, as they are inherently immunocompromised due to circulatory impairment and elevated inflammatory cytokines. Advancing age (55+), diabetes, and hypertension further increase infection risk and worsen CAD. Those with congenital or valvular heart disease and post-cardiac surgery patients also face high infection risks and must adhere to vaccination protocols, particularly for pneumococcal vaccine. (12)

Pneumococcal conjugate vaccine (PCV13) should be administered first, followed by the pneumococcal polysaccharide vaccine (PPSV23) after eight weeks. (13)

Vaccination in Cardiovascular Diseases – View of Scientific Authorities

Table 2 lists vaccines with Class recommendations for adults with cardiovascular and related chronic conditions. (13)

Table 2: Approved Class I Vaccine Recommendations in High-Risk Adults

Leading health organizations strongly recommend pneumococcal and influenza vaccination for patients with chronic cardiovascular disease. The Centers for Disease Control and Prevention/Advisory Committee on Immunization Practices (CDC/ACIP) advises pneumococcal vaccination for all adults over 50 and high-risk cardiovascular patients, alongside annual influenza vaccination for those with chronic heart and lung diseases. (14) Table 3 summarizes key vaccination recommendations from major global and national health authorities. 

Table 3: Pneumococcal Vaccination Recommendations by Leading Health Organizations

Additional recommended vaccines include Hepatitis B, which supports liver and overall health, and the shingles (herpes zoster) vaccine, as heart failure patients are prone to outbreaks due to stress, viral infections, and immune dysfunction.(12)

Effectiveness of Pneumococcal Vaccination in Improving Cardiovascular Outcomes

Vaccination significantly reduces hospitalizations and cardiovascular complications. A meta-analysis of 15 studies (347,444 patients) showed that pneumococcal vaccination reduced all-cause mortality by 24% (HR: 0.76, 95% CI: 0.66–0.87, p< 0.001) and myocardial infarction (MI) by 27% (HR: 0.73, 95% CI: 0.56–0.96, p = 0.02). (17) Another meta-analysis of seven studies (163,756 participants) showed pneumococcal vaccination reduced all-cause mortality by 22% (HR: 0.78, 95% CI: 0.73–0.83, p < 0.001). These findings highlight pneumococcal vaccination as a crucial preventive strategy for individuals at high cardiovascular risk, particularly those aged ≥65 years. (18)

Overcoming Barriers to Vaccination in Cardiac Patients – Multi-stakeholder Approach

Vaccine adherence remains low due to concerns about side effects, physician hesitancy, and cost. While cost is a barrier, hospitalization expenses for preventable infections are far higher. To improve adherence, public health initiatives, patient education, and enhanced accessibility are key. Effective strategies include patient messaging and community education to emphasize vaccines as essential for reducing cardiovascular risk and improving long-term health. (19)

Take Home Message

• CVD causes 24.8% of all deaths in India, with earlier onset and high premature mortality-highlighting the need to reduce preventable complications and secondary risks.
• Patients with CVD face a 3.3-fold higher risk of pneumonia and a 9.9-fold higher risk of invasive pneumococcal disease, which can cause acute and long-term myocardial damage.
• Pneumococcal vaccination lowers all-cause mortality by up to 24% and reduces myocardial infarction risk by 27%, supporting its role in cardiovascular risk reduction.
• API recommends pneumococcal vaccination for adults aged 18–49 with comorbidities, including chronic heart disease, and for all adults aged above 50.
• Despite strong endorsements from CDC, AHA, ESC, and Indian consensus guidelines, vaccine uptake in cardiac patients remains low-necessitating targeted education and public health action.
