Section E. Cardiovascular System Conditions

Objectives

Provide a consistent evidential and disability-evaluation framework for Veterans Affairs adjudication of cardiovascular conditions and cold-injury residuals, rather than a broader public-health strategy or budgeted programme.[1][2][3]The framework covers hypertensive vascular disease, arteriosclerotic and rheumatic heart disease, congenital defects, cardiovascular consequences of qualifying amputations, and long-term disability following cold exposure.[1][4][5][3]

• Define hypertension and isolated systolic hypertension using blood-pressure thresholds, distinguish pre-hypertension from compensable hypertension, and base disability evaluations on predominant qualifying readings.[1][6][7]
• Establish service connection and disability evaluations through competent clinical evidence, including direct, presumptive and secondary service connection, as well as post-service diagnoses where applicable.[8][2]
• Assess cardiovascular severity through objective findings, including cardiac hypertrophy or dilatation, metabolic equivalents, left ventricular ejection fraction, congestive-heart-failure history and documented arteriosclerotic heart disease.[9][2][5]
• Recognise and evaluate acute, latent and chronic cold-injury consequences, including frostbite, immersion foot, vascular and neurological effects, skin disorders, musculoskeletal impairment and functional limitations.[3][10]
• Support consistent recognition of cold-injury residuals among confirmed Chosin Reservoir Campaign participants, for whom extreme-cold exposure may be conceded despite absent contemporaneous treatment records.[10][11]

Implementation

Implement the framework through case-specific clinical review, regulatory rating criteria, examination requirements and adjudicative safeguards.[8][7][2]The extracts identify no programme-wide governance structure, routine reporting system, performance indicators, financing arrangements or institutional accountability mechanism beyond these evidential and decision-making procedures.[1][8][12][2][3]

• Confirm hypertension ordinarily through blood-pressure readings taken two or more times on at least three different days, while applying specified exceptions for reevaluation claims and previously diagnosed hypertension controlled by medication.[8]
• Review readings from the relevant claim period, determine the range containing the most qualifying competent and credible readings, and use that predominant range to assign the evaluation.[7][12]
• Consider continuous medication and the history of pre-medication diastolic pressure when deciding whether otherwise non-compensable current readings qualify for a 10 per cent hypertension evaluation.[8][7]
• Seek medical clarification or an opinion where recorded readings conflict with a diagnosis, where the evidence is unclear, or where the available examination evidence does not adequately represent cardiovascular disability.[6][2]
• Require objective evidence for arteriosclerotic heart disease, such as electrocardiogram, treadmill exercise testing, cardiac catheterisation or angiography; do not treat chest pain alone as diagnostic confirmation.[9]
• Document cardiac hypertrophy, dilatation and continuous medication needs through objective tests, including electrocardiogram, echocardiogram or X-ray.[9]
• Use metabolic-equivalent testing for relevant cardiovascular conditions unless testing is medically contraindicated, left ventricular ejection fraction is 50 per cent or less, qualifying congestive-heart-failure circumstances apply, or a 100 per cent evaluation is otherwise available.[9][2]
• Permit estimated metabolic equivalents where exercise testing cannot be undertaken for medical reasons, provided the examiner attributes the estimate solely to service-connected cardiovascular disease.[2]
• Use left ventricular ejection fraction where non-service-connected conditions affect metabolic equivalents and a cardiovascular-specific estimate cannot be made, or otherwise resolve reasonable doubt in the Veteran’s favour using the most advantageous evidence.[2]
• Interpret left ventricular ejection fraction below 30 per cent as supporting a 100 per cent evaluation and values from 30 to 50 per cent as supporting a 60 per cent evaluation under the relevant cardiovascular criteria.[5]
• Evaluate hypertension separately from hypertensive heart disease and other heart disease, and distinguish rheumatic heart disease from hypertensive or arteriosclerotic disease where required.[13][4]
• Grant secondary service connection, when claimed and supported, for specified arteriosclerotic manifestations associated with service-connected hypertension, including cerebral arteriosclerosis or thrombosis with hemiplegia, nephrosclerotic renal impairment, myocardial damage and coronary occlusion.[2]Assign the effective date as the later of the claim date or the date entitlement arose.[13]
• Assess cold-injury claims by determining whether injury occurred in service and whether an identifiable intercurrent non-service-connected cause explains the current residual; where no such cause can be determined, apply reasonable doubt in the Veteran’s favour.[10][11]
• Evaluate separately diagnosed cold-injury residuals, including amputations, squamous cell carcinoma, scars, peripheral neuropathy, Raynaud’s phenomenon and muscle atrophy, unless already used to support an evaluation under the applicable diagnostic code.[10]Evaluate each affected body part separately and combine evaluations under the cited regulations.[10]

Monitoring & Evaluation

The material sets out an evidential and adjudicative framework for evaluating cardiovascular conditions and cold-injury residuals for service connection and disability-rating purposes, rather than a population-health monitoring programme. It relies on clinical measurements, diagnostic testing, examination findings, medical opinions and review of claim-period evidence.[1][3]

• Assess hypertension using current blood-pressure readings during the claim period, including whether the predominant diastolic pressure was at least 100 before medication controlled symptoms when deciding whether the applicable exception supports a 0 or 10 per cent evaluation.[8]
• Confirm hypertension diagnoses through readings taken two or more times on at least three different days, except in specified circumstances such as reevaluation claims or previously diagnosed hypertension controlled by medication; for reevaluation of previously diagnosed hypertension, obtain three readings on the examination day.[8]
• Distinguish pre-hypertension, generally defined as systolic pressure of 120 to 139 mmHg or diastolic pressure of 80 to 89 mmHg, from hypertension meeting the regulatory definition for disability purposes. Do not award service connection solely on a pre-hypertension diagnosis where readings do not meet that definition, unless conflicting qualifying readings warrant clarification.[6]
• Record competent and credible systolic and diastolic readings, compare them with the relevant evaluation ranges, and identify as predominant the range containing the greatest number of qualifying readings, subject to the stated evidential rules.[7]
• Use representative valid evidence, generally emphasising predominant current readings for the period relevant to the effective date, and stage evaluations where different blood-pressure ranges are supported for at least one month.[7][12]
• Apply the benefit-of-the-doubt provisions where evidence is in relative balance between different evaluation levels for the same period, or where non-service-connected conditions affect metabolic-equivalent findings and cardiovascular-specific findings cannot be separated.[7][2]
• Seek medical clarification or an opinion where the evidence is unclear, including where a recorded pre-hypertension diagnosis conflicts with readings that meet the hypertension definition.[6]
• Require objective testing for arteriosclerotic heart disease, such as electrocardiogram, treadmill exercise testing, cardiac catheterisation or angiography; chest pain alone does not establish the diagnosis.[9]
• Document cardiac hypertrophy, cardiac dilatation and the need for continuous medication through objective evidence, including electrocardiogram, echocardiogram or X-ray findings.[9]
• Use metabolic equivalents, or METs, testing for specified cardiovascular conditions unless exercise testing is medically contraindicated, left ventricular ejection fraction is 50 per cent or less, chronic congestive heart failure is present, more than one episode of congestive heart failure occurred in the prior year, or a 100 per cent evaluation is available on another basis.[9][2]
• Permit estimated METs where exercise testing cannot be conducted for medical reasons, provided the examiner attributes the estimate solely to the service-connected cardiovascular disability. Use left ventricular ejection fraction where it is considered more accurate when other conditions affect METs, or resolve reasonable doubt in the claimant’s favour where appropriate.[2]
• Apply left ventricular ejection fraction thresholds in relevant cardiovascular evaluations: a value below 30 per cent corresponds to a 100 per cent evaluation, while a value from 30 to 50 per cent corresponds to a 60 per cent evaluation.[5]
• Consider evidence of acute, latent and chronic cold-injury manifestations, including vascular, neurological, skin, musculoskeletal and functional effects such as pain, cold sensitisation, numbness, oedema, ulceration, weakness and joint stiffness.[3][10]
• Assess whether cold injury occurred during service and whether an intercurrent non-service-connected cause explains the residual disability. Where no such cause can be identified, grant service connection while resolving reasonable doubt in the Veteran’s favour.[10]
• Evaluate separately diagnosed cold-injury residuals and affected body parts, including amputations, squamous cell carcinoma, scars, peripheral neuropathy, Raynaud’s phenomenon and muscle atrophy, unless already used to support an evaluation under the specified diagnostic code.[10]
• Concede extreme-cold exposure for confirmed participants in the Chosin Reservoir Campaign because frostbite may have been untreated and absent from service treatment records.[10][11]

The extract identifies examinations, medical opinions, objective tests, evidential review and procedures for clarifying medical reports as operational controls.[6][9][3]It does not specify programme-level indicators, performance targets, reporting schedules, surveillance arrangements, a formal evaluation plan, or organisational accountability mechanisms.[1][2][10]
