How the Board ruled on hypertension claims, 2021–2025

Hypertension (direct service connection)

Direct (began in or was caused by service), or theory not stated in the Board order

49.5% granted of 3,782 decided cases (margin of error 47.9–51.1%). 1,872 granted, 1,910 denied, 4,662 sent back to VA (remanded, not decided), 837 dismissed.

What convinced the Board in granted cases

• The Board granted when medical studies supported a link to an in-service exposure. Most often this was the 2018 National Academy of Sciences finding of 'sufficient' evidence linking high blood pressure to Agent Orange, either on its own or cited in a doctor's opinion. (9 of 14 decisions read; e.g. A24070250, 21015464, 24015030)
• A favorable opinion that reviewed the record, cited supporting literature, and addressed other risk factors such as obesity or smoking was given high weight. This included four from private or non-VA doctors, and in several cases no medical opinion contradicted it. (6 of 14 decisions read; e.g. 21052121, 21072106, 24015030)
• Negative VA opinions were given less weight when they did not consider the 2018 NAS update, did not address every theory raised, did not explain why one risk factor outweighed an in-service exposure, or gave no reason for the conclusion. (5 of 14 decisions read; e.g. 23027653, 21015464, A25039396)

Common reasons in denied cases

• A thorough VA opinion against the claim was unrebutted, or it outweighed a private opinion that gave a conclusion without a rationale or did not address the limits of the study it relied on. (7 of 19 decisions read; e.g. 24009528, 21002099, 21062820)
• The only evidence linking high blood pressure to service was the veteran's own opinion, which the Board found not competent on a complex medical question. In one case, the submitted articles did not name hypertension. (6 of 19 decisions read; e.g. 22002627, 22010800, A21003205)
• High blood pressure was first diagnosed decades after service, with no readings or symptoms in service and no credible account of continuous treatment since. (4 of 19 decisions read; e.g. A21013049, 21023639, A24027758)

Hypertension (exposure claims)

Exposure (e.g. Agent Orange, Camp Lejeune, burn pits)

56.5% granted of 361 decided cases (margin of error 51.4–61.5%). 204 granted, 157 denied, 471 sent back to VA (remanded, not decided), 20 dismissed.

What convinced the Board in granted cases

• Negative VA opinions lost weight when they were conclusory, ignored the 2018 National Academy of Sciences update, relied on wrong blood pressure facts, or skipped a theory raised. One private opinion citing research was persuasive. (6 of 13 decisions read; e.g. 21009620, 22046055, 21023913)
• The Board relied on the 2018 National Academy of Sciences finding of 'sufficient' evidence linking high blood pressure to Agent Orange, for veterans with presumed or conceded herbicide exposure. (8 of 13 decisions read; e.g. A24025364, 21041236, 21011505)
• In later decisions, high blood pressure had been added by law to the list of conditions presumed linked to herbicide exposure, and no other risk factor was found to explain it. (3 of 13 decisions read; e.g. A25008741, 22054431, 22053200)

Common reasons in denied cases

• A thorough VA opinion found no link, pointing to another clear cause, normal blood pressure in service, or studies showing the specific exposure (such as Camp Lejeune water) does not raise the risk. (4 of 11 decisions read; e.g. 22003014, 21030009, 21075526)
• The claimed herbicide exposure was not established. Service records did not show service in a qualifying location, and the veteran's general statements were not enough to prove exposure. (5 of 11 decisions read; e.g. A25034852, 21044997, A21013330)
• No medical opinion linked the high blood pressure to service. The veteran's own belief was not competent evidence, and in one case the veteran missed scheduled VA exams. (3 of 11 decisions read; e.g. 22049429, A21013330, 21069202)

Hypertension secondary to any service-connected condition

Secondary (caused or worsened by a service-connected condition)

41.6% granted of 793 decided cases (margin of error 38.2–45.1%). 330 granted, 463 denied, 1,816 sent back to VA (remanded, not decided), 77 dismissed.

What convinced the Board in granted cases

• The Board granted when a private or treating doctor explained how the service-connected condition raised blood pressure, such as through stress, sleep apnea, or diabetes, and cited medical literature. (6 of 10 decisions read; e.g. 24009647, 22037537, 23026506)
• Several grants accepted obesity as a middle step: a service-connected condition limited activity, causing weight gain that led to high blood pressure. (3 of 10 decisions read; e.g. 22040247, A25006716, A25026400)
• VA opinions lost weight when they were not fully reasoned or did not address the veteran's actual theory, such as obesity as an intermediate step. (2 of 10 decisions read, few decisions; e.g. A21004556, A25006716)

Common reasons in denied cases

• No medical opinion supported the link; the only link was the veteran's own belief, which is not competent evidence for this complex medical question. (6 of 10 decisions read; e.g. 21047049, 21045280, 21003125)
• Where opinions existed, a one-sentence private opinion with no rationale carried little weight, while a VA opinion explaining that blood pressure was controlled and not worsened carried more. (2 of 10 decisions read, few decisions; e.g. 21041719, A22017248)
• High blood pressure was first found many years after service, with normal readings in service or soon after. (3 of 10 decisions read; e.g. A24060299, 21016213, 24021197)

Hypertension secondary to PTSD

Secondary (caused or worsened by a service-connected condition)

41.2% granted of 153 decided cases (margin of error 33.7–49.1%). 63 granted, 90 denied, 385 sent back to VA (remanded, not decided), 24 dismissed.

What convinced the Board in granted cases

• Negative VA opinions lost weight when they did not address aggravation or the secondary question, said no literature exists when the record had some, used wrong dates, or gave general statements not tied to the veteran. (12 of 22 decisions read; e.g. 23028602, A21010169, 23036472)
• A private opinion carried the claim when it reviewed the history and claims file, cited medical literature, and gave a full explanation, sometimes from a treating physician. (6 of 22 decisions read; e.g. A22017237, 24005092, 21065080)
• Grants often followed a specific pathway: PTSD leading to weight gain or obesity (including from medications or poor sleep), or to alcohol use, which then led to high blood pressure. (6 of 22 decisions read; e.g. A23025439, 23050448, 22025022)

Common reasons in denied cases

• The Board denied when VA examiners explained that stress can raise blood pressure briefly but that literature does not show PTSD causes or permanently worsens hypertension, and no adequate opinion said otherwise. (9 of 16 decisions read; e.g. A21009129, 21013851, 21015232)
• Examiners pointed to other causes or timing, such as age, weight, diet, family history, or high blood pressure that started before the PTSD. (4 of 16 decisions read; e.g. 21013851, 21064106, 21019558)
• Private opinions with no explanation and the veteran's own belief about the cause were given little or no weight. (4 of 16 decisions read; e.g. 21063945, 21027627, 21064106)

Hypertension secondary to diabetes

Secondary (caused or worsened by a service-connected condition)

32.1% granted of 137 decided cases (margin of error 24.9–40.3%). 44 granted, 93 denied, 293 sent back to VA (remanded, not decided), 18 dismissed.

What convinced the Board in granted cases

• The Board granted when a VA or private opinion explained that diabetes is a known cause of high blood pressure, for example through hardening of the arteries, often citing literature. (6 of 15 decisions read; e.g. 23026506, A25033314, 24008434)
• A negative opinion lost weight when it rested on a wrong premise (such as diabetes not yet being service connected), skipped aggravation, or missed relevant blood pressure readings. (4 of 15 decisions read; e.g. 21019524, 21071520, 21018191)
• In several grants the key step was getting diabetes itself service connected (often through the herbicide or toxic exposure presumption), after which high blood pressure followed. (5 of 15 decisions read; e.g. 24030209, A23001697, A25033314)

Common reasons in denied cases

• The Board denied when high blood pressure began before the diabetes and there was no objective evidence that diabetes made it worse over time. (5 of 13 decisions read; e.g. 21048766, A21002728, A24032296)
• Claims failed because diabetes was not service connected, so high blood pressure could not be secondary to it. (4 of 13 decisions read; e.g. 21053917, 22004103, 22020006)
• Examiners found no diabetic kidney involvement, which they said would be expected if diabetes drove the blood pressure, or named another cause such as obesity. (4 of 13 decisions read; e.g. 21038425, 21076077, A24032296)

Hypertension secondary to depression / psychiatric disorder

Secondary (caused or worsened by a service-connected condition)

52.1% granted of 94 decided cases (margin of error 42.1–61.9%). 49 granted, 45 denied, 192 sent back to VA (remanded, not decided), 8 dismissed.

What convinced the Board in granted cases

• The Board granted when a private opinion cited medical literature on how mental health conditions raise blood pressure and applied it to the veteran's record, outweighing or balancing a negative VA opinion. (6 of 12 decisions read; e.g. 22042063, A25006716, 23001727)
• VA examiners' own favorable findings also supported grants, including that the psychiatric condition or its medications worsened the veteran's blood pressure, even if it did not cause it. (5 of 12 decisions read; e.g. A25037553, 21075357, 24015818)
• Negative VA opinions lost weight when they were conclusory with no literature, or demanded permanent worsening when even temporary worsening counts. (2 of 12 decisions read, few decisions; e.g. 24030727, A24040142)

Common reasons in denied cases

• The Board denied when VA examiners gave reasoned opinions, addressing both cause and worsening, that the psychiatric condition did not affect the blood pressure, and no equally reasoned opinion rebutted them. (7 of 14 decisions read; e.g. 22030370, 22036430, 23029957)
• Claims failed when the only support was the veteran's own belief about the cause, or a private opinion saying only that one condition 'may' worsen the other. (4 of 14 decisions read; e.g. 21034893, 21052698, 22036430)
• Some claims failed because the psychiatric condition was not service-connected, or because the veteran was not shown to have a hypertension diagnosis. (4 of 14 decisions read; e.g. A24009263, 21006189, 21052935)

Hypertension secondary to sleep apnea

Secondary (caused or worsened by a service-connected condition)

67.4% granted of 46 decided cases (margin of error 53.0–79.1%). 31 granted, 15 denied, 100 sent back to VA (remanded, not decided), 3 dismissed.

What convinced the Board in granted cases

• The Board granted when a private or treating physician explained how sleep apnea raises or worsens blood pressure, cited medical literature, and applied it to this veteran's records, often addressing aggravation. (6 of 12 decisions read; e.g. 22037537, A21011196, A25008807)
• Negative VA opinions lost weight when they ignored aggravation, gave no adequate rationale, relied only on missing service records, cited literature generically, or rested on inaccurate facts. (6 of 12 decisions read; e.g. A21011196, 23025583, 24025927)
• A long-term treating specialist's opinion that sleep apnea makes hypertension worse carried weight because of the in-person exam and knowledge of the veteran's history, even with a short rationale. (2 of 12 decisions read, few decisions; e.g. A25021461, A21011196)

Common reasons in denied cases

• Reasoned VA opinions that reviewed the record and explained no causation or aggravation were found more persuasive, including over general articles that did not address the veteran's type of hypertension. (5 of 10 decisions read; e.g. 21067147, 21070409, A24016616)
• The only support was the veteran's own belief that sleep apnea caused the hypertension, which the Board found was not competent on this complex medical question. (4 of 10 decisions read; e.g. A21011898, A24016616, 23031031)
• Other denials turned on direct-service theories or the primary condition: a private opinion based on mistaken service facts, transient in-service readings, or sleep apnea not service-connected. (3 of 10 decisions read; e.g. 21071675, A23022319, 22017854)

Hypertension secondary to heart disease

Secondary (caused or worsened by a service-connected condition)

46.9% granted of 32 decided cases (margin of error 30.9–63.6%). 15 granted, 17 denied, 109 sent back to VA (remanded, not decided), 5 dismissed.

What convinced the Board in granted cases

• The Board granted when a medical opinion, most often from a VA examiner, gave an adequate rationale that the service-connected heart disease caused or aggravated the hypertension. (4 of 8 decisions read; e.g. 22024685, 21006053, 24008658)
• Negative VA opinions lost weight when they answered the reverse question (whether hypertension causes heart disease) or demanded a more certain link than the at-least-as-likely standard. (2 of 8 decisions read, few decisions; e.g. 24020786, 21023847)

Common reasons in denied cases

• Reasoned VA opinions went unrebutted when they explained that hypertension is a risk factor for heart disease rather than the reverse, or that the blood pressure had stayed controlled. (4 of 14 decisions read; e.g. 22041125, 21008817, 21043001)
• Many denials addressed direct service connection: normal blood pressure in service, diagnosis decades later, and the veteran's own belief, which was not competent medical evidence. (5 of 14 decisions read; e.g. 21068260, 21035646, 21030068)
• Some denials found the heart disease itself was not service-connected, so hypertension could not be granted as secondary to it. (2 of 14 decisions read, few decisions; e.g. A21003499, 22053316)
