The risk for major stroke is high shortly 11 after a symptomatic event but less so several months after an event or with asymptomatic disease buy discount flomax 0.2 mg line mens health 2011.

Renal artery stenosis can precipitate hypertensive crises associated with pulmonary edema, hypertension resistant to treatment, and rapidly worsening renal 13 dysfunction. Revascularizing asymptomatic extracranial carotid disease beyond medical therapy has uncertain value, although recent guidelines support such interventions for patients at higher risk for stroke and low risk for periprocedural 11 adverse events. Many studies are single arm, and most focus on patency (lack of restenosis) and repeated revascularization over a relatively short period. Angioplasty remodels the artery by expansion and accommodates the atherosclerotic plaque to expand the vessel lumen. This procedure usually causes dissection of the plaque that may or may not impair blood flow. Angioplasty is limited in the short term by acute recoil of the artery and flow-limiting dissections, which may cause abrupt closure of the artery. In the intermediate time frame, overexuberant neointimal hyperplasia and negative remodeling of the artery may lead to symptomatic restenosis. Despite these limitations, balloon angioplasty can achieve durable results, particularly with shorter lesions, and is less likely than stenting to obstruct side branches associated with the lesion. Both rapid-exchange and over-the-wire platforms are available, as well as short and long shaft lengths for lesions close to or farther from the access site. Stent implantation requires aspirin therapy and an adenosine receptor antagonist (i. Balloon-expandable stents have greater radial strength and are less likely to move on deployment, which is important for ostial placement. Such stents can be crushed by external compression and are therefore avoided outside the torso. They are sometimes used to treat tibial disease, but only for critical limb ischemia, for which long-term patency may be less of an issue once tissue healing has occurred. Nitinol stents reexpand on compression and are therefore used outside the torso, where external compression is more likely to occur. They may also be used in tortuous arteries, where they probably conform better than balloon-expandable stents. More recent self-expanding stent designs are more durable and less likely to fracture. Nitinol stents cannot be overdilated if the stent is undersized for the artery, which may lead to stent malapposition or even embolization. Drug-Eluting Peripheral Stents Earlier attempts at coating peripheral self-expanding stents were initially associated with less restenosis in the short term but were unsuccessful in longer follow-up, partly because of inferior stent platforms 17-19 20 21 prone to fracture. More durable stent designs and drug elution with everolimus or paclitaxel offer lower rates of restenosis. In one series, covered stents that cross the knee joint were associated with higher rates of occlusion and major 26 amputation than those deployed above the knee (34% versus 10%). Disadvantages of covered stents 21 include unintentional occlusion of important branch vessels, concerns about the risk for late stent thrombosis, and whether restenosis was merely delayed rather than prevented. A, Perforation after directional atherectomy shown enlarged in the lower right box (arrow). Drug-Coated Balloons Balloons coated with antirestenosis agents (drug-eluting balloons) represent an exciting development. This technology uses a non–stent-related method to deliver drugs such as paclitaxel into the arterial wall after conventional angioplasty treatments. Compared with plain balloon angioplasty, drug-coated balloons 27-30 have less restenosis and repeat revascularization in the femoral-popliteal arteries. Drug-coated balloons also offer a lower risk of restenosis compared with plain balloon angioplasty for treating in- 31 stent restenosis lesions. Late follow-up of two randomized trials at 2 and 5 years shows a sustained benefit on patency and repeat revascularization with drug-coated versus plain balloon angioplasty in 30,32 femoral-popliteal arteries, without safety concerns of aneurysm or late stenoses. Compared to plain balloon angioplasty, one randomized trial showed a lower risk for repeat 33 revascularization but no effect on major amputation or mortality. Differences in drug-coating techniques and eluting agents could explain the lackluster results of drug-coated balloons below the knee, 18 and the question of their value requires further evaluation.

Guiding patients and families to understand prognosis and express goals of care is crucial for them to share in decisions about the intensity and timing of care order online flomax prostate cancer forum. When a cardiac condition is likely to cause or accelerate death within the coming year generic flomax 0.2 mg visa prostate video surgery, cardiac specialists may often have a good vantage point from 2 which to survey the disease trajectory and steer the direction of care order flomax 0.4 mg mastercard mens health wiki. Ideally, patients continue to the end guided by health care providers who maintain longitudinal relationships with them and apply palliative care principles to smooth this journey. This chapter clarifies main concepts and provides practical approaches to the management of patients with cardiovascular disease nearing the end of life (Table 31. Worsening disease should trigger preparation with patients and families, but without specifically answering the question of how much time remains, which is usually bounded by wide uncertainty. Shared decisions include a broad spectrum of potential interventions beyond those relating to resuscitation preferences. Deactivation of the defibrillation function of implantable cardioverter-defibrillators should be explained and offered regularly to patients with poor prognosis and must be done before transition to hospice. Palliative care specialist consultation may be particularly helpful to facilitate decision making within challenging family dynamics and to improve relief of refractory symptoms. Clinicians with existing relationships should shoulder the primary responsibility for presenting an end-of-life plan consistent with values and goals expressed by patient and family. The transition separating “do everything” from hospice may be bridged through a phase of “quality survival” during which patients increasingly weigh the benefits, risks, and burdens of initiating or continuing life-sustaining treatments. Revision of the medical regimen for symptom relief and quality of life may involve discontinuation of some recommended therapies and addition of therapies not usually recommended. The end-of-life plan should honor patient preference for the site of death as feasible, with agreement on a “plan B” if that becomes unsupportable. Integration of Palliative Care Into Cardiovascular Care Palliative care is designed to improve quality of life for patients and their families through anticipation of declining health status and major events, clarification of goals of care, relief of physical symptoms, 3 provision of psychosocial and spiritual support, coordination of care, and assistance with bereavement (Fig. However, many providers of cardiovascular care do not distinguish between palliative care and hospice or understand the 6 indications for these services. Examples of intervention: 2, Inactivation of defibrillation function of implantable cardioverter-defibrillator. Provision of supportive care by the usual care team has been designated as primary palliative care, to distinguish it from secondary or subspecialty palliative 5 care. Secondary (Subspecialty) Palliative Care Palliative care clinicians receive specific training in management of refractory symptoms and facilitation of difficult care planning in life-threatening illnesses. Hospice and Palliative Medicine is a recognized 7 medical subspecialty in the United States, Canada, England, Ireland, Australia, and New Zealand. Hospice The term hospice is used to describe a specific model of palliative care offered to patients who are at the end of life with a terminal disease when curative or life-prolonging therapy is no longer a focus of treatment. The 6-month period is rarely reached, but patients who survive longer can usually continue to receive hospice benefits if the prognosis remains poor. Palliative Care Consultation Indications Various specialties may assume the central role in coordination of patient care at different stages of disease progression, often with transition of leadership from primary care to cardiology to palliative 11 care (eFig. Shared ownership and planning around palliative care needs can improve communication and understanding of patient goals and achieve better end-of-life experiences. Formal consultation may be particularly helpful when symptoms remain intolerable or when medical decision making is particularly challenging. For example, since 2013, national standards require centers that offer permanent mechanical circulatory support to include palliative care specialists as part of the team from 12 evaluation through to death. Similar mandates are anticipated for palliative consultation to review options and “what-ifs” for other major cardiac interventions with high mortality and morbidity. Retrospective analysis of Medicaid patients in four New York hospitals from 2004 to 2007 indicated that palliative care consultation during hospitalization for exacerbation of chronic fatal illness, including heart failure, was associated with a $4000 lower cost for discharged patients and $7000 lower cost for patients dying during that 13 hospitalization. In a large randomized trial in intensive care settings, however, palliative care specialist supervision of at least two structured family meetings and written information did not decrease anxiety or depression and may have increased post-traumatic stress for families 15 compared to similar intervention led by the intensive care unit teams. To be effective, palliative care consultations need to be targeted to the right patients at the right time and integrated thoughtfully into the overall plan of medical care. When done well, such discussions can help to align therapy with patient goals, improve quality of life for both patients and caregivers, and enhance the quality of medical decisions and symptom palliation. End-of-life discussions are sensitive and time-consuming and may be further complicated by discordant priorities of patients and their families. Almost half of older Americans report they have not 16 had any end-of-life planning discussion.
