The death of U.S. Senator Lindsey Graham at age 71 has prompted a clinical examination of aortic dissection and related cardiovascular pathologies.

美國參議員林賽·格雷厄姆於 71 歲時逝世，觸發了對主動脈剝離及相關心血管病理的臨床研究。

The preliminary findings from the medical examiner attribute the death of Senator Graham to an aortic dissection. This condition is characterized by a breach in the inner lining of the aorta, which facilitates the penetration of blood into the arterial wall, thereby creating a secondary channel and compromising the vessel's structural integrity. In the case of the Senator, this event was associated with arteriosclerotic cardiovascular disease, a condition typically driven by senescence, chronic hypertension, and the progressive hardening of the arteries.

法醫的初步結果將格雷厄姆參議員的死因歸類為主動脈剝離。這種情況的特徵是主動脈內層出現破裂，導致血液滲入動脈壁，從而形成第二條通道，並損害血管的結構完整性。在參議員的案例中，這次事件與動脈硬化性心血管疾病相關，這種疾病通常由衰老、慢性高血壓以及動脈漸進性硬化所驅動。

Distinctions must be drawn between three primary aortic pathologies: aneurysms, dissections, and ruptures. An aneurysm constitutes a gradual dilation of the aortic wall, whereas a dissection is an acute tear that may occur independently of prior dilation. A rupture represents the terminal failure of the wall, resulting in catastrophic hemorrhage into the thoracic cavity or the pericardial sac. While the Senator's condition aligned with age-related arterial degradation, other instances—such as the death of journalist Grant Wahl at age 49—demonstrate a divergence in etiology. In younger cohorts, aortic failure is frequently linked to inherited connective tissue disorders, such as mutations in the FBN1 gene associated with Marfan syndrome, rather than cumulative cardiovascular wear.

必須區分三種主要的主動脈病理：主動脈瘤、剝離與破裂。主動脈瘤是指主動脈壁逐漸擴張，而剝離則是一種急性撕裂，可能在先前未擴張的情況下發生。破裂代表血管壁的最終失效，導致胸腔或心包囊發生災難性出血。雖然參議員的情況符合與年齡相關的動脈退化，但其他案例——例如 49 歲逝世的記者格蘭特·沃爾——則顯示出病因的差異。在較年輕的群體中，主動脈失效通常與遺傳性結締組織疾病有關，例如與馬凡氏綜合症相關的 FBN1 基因突變，而非心血管的累積性損耗。

Diagnostic challenges persist due to the symptomatic overlap between aortic dissection and myocardial infarction. Clinical identification often necessitates computed tomography (CT) scans to differentiate the condition from more benign abdominal or thoracic ailments. Institutional responses to these risks include targeted screening for high-risk demographics—specifically men aged 65 to 75 with a history of smoking—and the implementation of genetic surveillance programs. The New York City medical examiner's office has established the GIFTS program to provide genetic testing for living relatives of deceased individuals to identify asymptomatic carriers of hereditary variants.

由於主動脈剝離與心肌梗塞的症狀重疊，診斷挑戰依然存在。臨床識別通常需要透過電腦斷層掃描 (CT) 掃描，以將此情況與較輕微的腹部或胸部疾病區分開來。針對這些風險的機構回應包括對高風險族群（特別是 65 至 75 歲且有吸菸史的男性）進行針對性篩查，以及實施基因監測計劃。紐約市法醫辦公室建立了 GIFTS 計劃，為死者的生還親屬提供基因檢測，以識別遺傳變異的無症狀攜帶者。

Senator Graham's death underscores the prevalence of age-related aortic dissection and the critical necessity of blood pressure management and genetic screening for at-risk populations.

格雷厄姆參議員的逝世凸顯了年齡相關主動脈剝離的普遍性，以及對高風險人群管理血壓與進行基因篩查的緊迫必要性。
