Chronic heart failure (CHF) is associated with frequent hospitalizations and high mortality. It affects more than 5 million individuals in the USA, and another 660,000 new cases are diagnosed each year; overall, heart failure (HF) now accounts for 7% of all deaths from cardiovascular disease. Hypertension (HTN) increases the risk of development of HF and it precedes it in 75% of cases. HF patients are nearly evenly divided between those with reduced left ventricular (LV) function or systolic dysfunction and those with preserved LV systolic function or diastolic dysfunction. The management of HTN in patients with CHF is challenging. Drugs such as beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, aldosterone receptor blockers, hydralazine and nitrates, which have shown mortality benefit in CHF and exert antihypertensive effects, should be used as first-line agents to control HTN in CHF. In addition, antihypertensive drugs such as alpha-receptor blockers that can increase mortality in HF should be avoided. The dihydropyridine group of calcium channel blockers are good antihypertensive medications with a neutral effect on mortality in patients with CHF. These may be used in CHF patients with refractory HTN. In patients with HF with reduced ejection fraction, HTN is treated differently in comparison to patients with HF with normal ejection fraction. This article reviews the treatment of essential HTN in patients at risk for developing HF, in the presence of HF and the latest developments in treatment that might benefit both HTN and HF management.
慢性心力衰竭(CHF)与频繁住院和高死亡率相关。在美国,有超过500万人受其影响,且每年有另外66万新病例被诊断出来;总体而言,心力衰竭(HF)目前占心血管疾病所致死亡总数的7%。高血压(HTN)会增加发生HF的风险,且在75%的病例中先于HF出现。HF患者在左心室(LV)功能降低或收缩功能障碍者与LV收缩功能保留或舒张功能障碍者之间几乎平分。CHF患者的HTN管理具有挑战性。诸如β受体阻滞剂、血管紧张素转换酶抑制剂、血管紧张素受体阻滞剂、醛固酮受体阻滞剂、肼屈嗪和硝酸盐等药物,已显示在CHF中具有降低死亡率的益处并发挥降压作用,应作为控制CHF患者HTN的一线药物使用。此外,可增加HF患者死亡率的抗高血压药物如α受体阻滞剂应避免使用。钙通道阻滞剂的二氢吡啶类是良好的抗高血压药物,对CHF患者的死亡率具有中性影响。这些药物可用于难治性HTN的CHF患者。在射血分数降低的HF患者中,与射血分数正常的HF患者相比,HTN的治疗有所不同。本文综述了有发生HF风险的患者、存在HF时原发性HTN的治疗以及可能有益于HTN和HF管理的最新治疗进展。
